                               (Amendment No. 4)

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

	(a)	On January 14, 1994, Highland and SHHH purchased 4,374,453 and 
1,458,151 shares of Class A Common Stock, respectively, from the Company in a 
public offering pursuant to a registration statement that had been declared 
effective by the Commission.  The purchase price for the shares sold to
Highland  was $75,000,000, which was paid to the Company in cash and was
provided by  $30,000,000 in margin loans from Salomon Brothers Inc to Highland,
capital  contributions to Highland from its partners, and the remainder in
loans from a  subsidiary, Highland Video Associates, L.P., to Highland.  The
purchase price  for the shares sold to SHHH was $25,000,000, which was paid to
the Company in  cash and was provided by a $15,000,000 loan from Doris to SHHH
and a $10,000,000  margin loan from Salomon Brothers Inc to SHHH.  See Item 6
for a description of  the pledge of the shares acquired by Highland and SHHH.

	(b)	On June 11, 1993, pursuant to a Stock Purchase Agreement of
even date,  John J. Rigas (including, with respect to 106,505 of his shares,
Doris N. Rigas,  his wife, as joint owner) sold 360,100 shares of Class A
Common Stock, and each  of Michael J. Rigas, Timothy J. Rigas and James P.
Rigas sold 193,300 shares of  Class A Common Stock (for a total of 940,000
shares of Class A Common Stock,  hereinafter referred to collectively as the
"Subject Shares"), to SHHH, in  exchange for $12,500,000 in 9% purchase money
demand notes.  Simultaneous with  the consummation of such transaction, SHHH
transferred the Subject Shares to  Ionian, which is also an affiliate of the
Rigas family, in exchange for  $12,500,000 cash (the "Cash Consideration"). 
The Cash Consideration was  borrowed by Ionian from a group of banks (the
"Lender Banks").  The Subject  Shares have been pledged by Ionian pursuant to a
pledge agreement between the  Agent for the Lender Banks and Ionian.

	In connection with such transactions, John J. Rigas (including, with 
respect to 106,505 of his shares, Doris N. Rigas, his wife, as joint owner), 
Michael J. Rigas, Timothy J. Rigas and James P. Rigas (the "Sellers"), SHHH and 
Ionian entered into a Stock Transfer and Proxy Agreement, a copy of which was 
filed as an exhibit to Amendment No. 3 and is incorporated herein by reference 
(the "Proxy Agreement").  See Item 6 of this Amendment No. 4 for a description 
of certain terms of the Proxy Agreement.

	(c)	Schedule B annexed hereto sets forth certain acquisitions of
Class A  Common Stock including those made by the persons listed on Schedule A
since the  filing of Amendment No. 3.  These acquisitions were made on an
individual basis  for investment purposes in over-the-counter open market
transactions.  The  source of the purchase price paid for each of these
acquisitions was the  respective personal funds of each of such persons. 
Schedule B hereto lists the  date, number of shares and purchase price of the
Class A Common Stock purchased  by each of such persons subsequent to the date
of the Original Schedule 13D,  including purchases since the date of Amendment
No. 3.

	The aggregate beneficial ownership of Class A Common Stock for each
person  filing this Amendment No. 4 as set forth on the various cover pages
hereto and  as set forth in Schedule C annexed hereto also includes shares of
Class A and

CUSIP No. 006848 10 5                 13D
                               (Amendment No. 4)

Class B Common Stock held by such persons prior to the above-referenced acqui-
sitions.  Such holdings were previously reported in the Schedule 13D Filings
and  on a Schedule 13G (the "Schedule 13G") filed with the Commission on
February 16,  1988.

ITEM 4.  PURPOSE OF TRANSACTION

	Highland and SHHH acquired their respective shares in January 1994 for 
investment purposes and such shares form part of the Rigas family holdings of 
Common Stock of the Company.  Doris, the general partner of SHHH, and Eleni,
the  general partner of Doris, are also filing persons with respect to the same 
1,458,151 shares of Class A Common Stock acquired by SHHH.  The general
partners  of Highland were filing persons prior to this Amendment No. 4.

	Ionian acquired the Subject Shares for investment purposes, as part of
a  partial restructuring of the Rigas family holdings of Class A Common Stock. 
See  also Item 6 with respect to the rights of the various parties with respect
to  the Subject Shares.  Iliad Holdings, the general partner of Ionian, is also
a  filing person with respect to the Subject Shares.

	The other shares of Class A Common Stock listed in Schedule B hereto
were  acquired by the persons listed in Schedule A hereto subsequent to the
filing of  the Original Schedule 13D in over-the-counter open market
transactions and, with  respect to the May 14, 1992 acquisitions, directly from
the Company, by the  persons listed in Schedule A hereto on an individual basis
for investment  purposes.

	The persons listed in Schedule A hereto (excluding Ellen K. Rigas),
both  prior to and after the above-referenced acquisitions, served and continue
to  serve as directors and officers of the Company and in such capacities are 
involved generally in the Company's management, business and operations.  The 
persons listed in Schedule A hereto, in their capacities as Class A and Class B 
stockholders, currently have the power to elect all seven of the seven members 
of the Company's Board of Directors pursuant to the Company's Certificate of 
Incorporation and the Stockholders' Agreement referenced in Items 6 and 7 
herein.

ITEM  5.  INTEREST IN SECURITIES OF THE ISSUER

	(a)	Each of the persons listed in Schedule A hereto owns shares of
Class A  Common Stock (other than James P. Rigas) and shares of Class B Common
Stock  (other than Daniel R. Milliard) of the Company.  Ionian (and Iliad),
SHHH (and  Doris and Eleni) and Highland own only shares of Class A Common
Stock.  The  Class B Common Stock owned by the persons on Schedule A is
convertible into  shares of Class A Common Stock on a one-to-one basis and is
therefore treated  for purposes of this statement as beneficial ownership of
shares of Class A  Common Stock.  Schedule C hereto sets forth, with respect to
the Limited Purpose  Group, each person listed in Schedule A, and Ionian (and
Iliad), SHHH (and Doris  and Eleni) and Highland, the aggregate number of
shares of Class A Common Stock,  and the percentage of outstanding Class A
Common Stock, which may be deemed to  be beneficially owned by the Limited
Purpose Group, each such person (in each

                               (Amendment No. 4)

case assuming that such person alone converts all of his or her shares of 
Class B Common Stock into shares of Class A Common Stock) and each such entity, 
as of the close of business on January 28, 1994.  Each person listed in 
Schedule A disclaims beneficial ownership of shares of Class A and Class B 
Common Stock owned directly by other persons listed in Schedule A.

        (b)     Schedule C sets forth with respect to each person listed in
Schedule A  and Ionian (and Iliad), SHHH (and Doris and Eleni) and Highland the
number of  shares of Class A Common Stock which may be deemed to be
beneficially owned by  such persons as to which each person has  (i) the sole
power to vote or to  direct the vote;  (ii) shared power to vote or to direct
the vote;  (iii) sole  power to dispose or to direct the disposition; and  (iv)
shared power to dispose  or to direct the disposition.  The right of each
person listed in Schedule A to  dispose of any shares of Common Stock (as
defined in Item 6 below) is subject to  certain provisions of the Stockholders'
Agreement as discussed in the third  paragraph of Item 6 below and the fourth
paragraph of Schedule C hereto.  The  right of Ionian to vote or dispose of any
shares is subject to the Proxy  Agreement described in Item 6 below and
Schedule C hereto.

        (c)     Except as set forth in Item 3 and Schedule B hereto which are 
incorporated herein by reference, no person listed in Schedule A has effected 
any transaction in the Class A or Class B Common Stock during the past sixty 
(60) days.

        (d)     Not applicable.

        (e)     Not applicable.


ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT 
         TO SECURITIES OF THE ISSUER

        Each of the individuals listed in Schedule A, as well as Dorellenic, a 
Pennsylvania general partnership, is a party to a Stockholders' Agreement, as 
amended, wherein they have agreed that so long as they are the holders and
beneficial owners in the aggregate of not less than 25% of the combined
voting power  of the issued and outstanding Common Stock, they shall vote their
shares of  Common Stock for the election of the directors designated by a
majority of the  voting power of the shares of Common Stock owned by them as a
group.  "Common  Stock" is defined in the Stockholders' Agreement to include
the Class A Common  Stock and the Class B Common Stock and any class or series
of any class of  capital stock into which such shares shall be converted, and
any other class or  series of any class of capital stock of the Company which
has voting power of  any nature.  Accordingly, the members of the Limited
Purpose Group identified in  Schedule A are acting as a group only with respect
to voting for the election of  directors and not for the purpose of acquiring,
disposing or otherwise voting  such securities.

                              Page 19 of 49 pages

CUSIP No. 006848 10 5                 13D
                               (Amendment No. 4)

        Since John J. Rigas has a majority of the voting power of the shares of 
Common Stock owned collectively by the Limited Purpose Group, he has the right 
by agreement to direct the vote of the shares of the other members of the 
Limited Purpose Group but only with respect to the election of directors, and 
he has the right to consent to a sale of shares held by the other members of
the  Limited Purpose Group as described below.

        The right of a party to the Stockholders' Agreement to dispose of
shares of  Common Stock listed in Item 5(b) and in Schedule C hereto, in the
absence of the  consent of the holders of a majority of the voting power of the
shares of Common  Stock owned by the parties to the Stockholders' Agreement as
a group, generally  is subject to the pro rata right of first refusal of the
other parties to the  Stockholders' Agreement in the event of a contemplated
Public Sale (as defined  in the Stockholders' Agreement) and to a right of
first refusal in the Company  and the other parties to the Stockholders'
Agreement in the event of a  contemplated Private Sale (as defined in the
Stockholders' Agreement) of any  shares of Common Stock by any party thereto. 
The Stockholders' Agreement also  requires in certain circumstances that a
decedent's stockholder's estate offer  to sell shares of Common Stock in such
estate to the other surviving  stockholders.

        Dorellenic itself is not included in the Schedule 13D Filings or this 
Amendment No. 4 as a member of the Limited Purpose Group since its share owner-
ship is set forth as being beneficially owned by each of its general partners 
who are themselves members of the Limited Purpose Group and are reporting such 
ownership hereby.

        Ionian has pledged the Subject Shares to the Agent for the benefit of
the  Lender Banks.  Pursuant to this pledge agreement, the Agent has certain
rights,  upon default and after notice and opportunity to cure, to vote the
Subject  Shares, and to foreclose on such collateral and, pursuant thereto, to
take  possession of, to vote or to dispose of the Subject Shares.

        Pursuant to the Proxy Agreement, Ionian has agreed not to pledge,
encumber,  sell, transfer, dispose of or otherwise assign, by operation of law
or otherwise, any of the Subject Shares without the express written consent
of each of  the Sellers, except pursuant to the pledge agreement with the Agent
discussed in  the preceding paragraph and as otherwise provided therein.  In
addition, the  Sellers have certain rights of first refusal over the Subject
Shares, and each  of the Sellers has the right to vote the respective Subject
Shares transferred  by such Seller pursuant to an irrevocable proxy.  The
irrevocable proxy is  subject to certain rights of the Agent pursuant to the
pledge agreement  discussed above.  Finally, under certain conditions, the
Proxy Agreement  requires Ionian to sell to the Sellers the Subject Shares, and
requires the  Sellers to purchase the same, at certain applicable prices as set
forth therein.   Such purchase and sale are subject to the further condition
that the Agent  releases the Subject Shares from the pledge agreement between
Ionian and the  Agent.

        Highland and SHHH have each pledged their 4,374,453 and 1,458,151 
respective shares of Class A Common Stock to Salomon Brothers Inc ("Pledgee")
as  collateral for margin loans described in Item 3 hereof.  Such margin loans
are

                               (Amendment No. 4)

also co-signed by John J. Rigas, Michael J. Rigas, Timothy J. Rigas and James
P.  Rigas.  Pursuant to such margin loans and related pledge documentation, the 
Pledgee has certain rights, upon default and after notice and opportunity to 
cure, to vote the pledged shares and to foreclose on such collateral and, 
pursuant thereto, to take possession of, to vote or to dispose of pledged
shares  to satisfy amounts outstanding under the respective margin loans.  For
these  purposes, the Pledgee's rights to sell pledged shares include the right
to do so  upon the failure to maintain any required collateral value for such
margin  loans.  The Company has agreed to maintain an effective shelf
registration  statement covering the potential resale of any such pledged
shares for so long  as any such margin loans remain outstanding.

1.      AMOUNT BENEFICIALLY OWNED

        LIMITED PURPOSE GROUP.  The Limited Purpose Group is deemed to
beneficially  own 17,631,448 shares of the Class A Common Stock of the Company,
which number  includes 97,949 shares of Class A Common Stock beneficially owned
by Dorellenic,  a general partnership in which each of the members of the
Limited Purpose Group  except Daniel R. Milliard are the sole general partners,
and 4,374,453 shares of  Class A Common Stock beneficially owned by Highland, a
general partnership in  which each of the members of the Limited Purpose Group
are the sole general  partners.  This number also includes 700 shares of Class
A Common Stock  beneficially owned by Daniel R. Milliard jointly with his
spouse and 300 shares  of Class A Common Stock held of record by Daniel R.
Milliard's spouse as trustee  for Daniel R. Milliard's children.  The shares
held jointly or individually by  Daniel R. Milliard's spouse are deemed to be
beneficially owned by Daniel R.  Milliard and are therefore included in the
shares deemed beneficially owned by  the Limited Purpose Group for purposes of
this statement.  Further, to the  extent that the shares deemed beneficially
owned by the other members of the  Limited Purpose Group are deemed
beneficially owned by John J. Rigas as  discussed below, the shares that are
held by Daniel R. Milliard's spouse  individually and jointly with her husband
are included in the shares deemed  beneficially held by John J. Rigas for
purposes of this statement.  The Limited  Purpose Group and each member of the
Limited Purpose Group disclaims beneficial  ownership of the shares of Class A
Common Stock held of record by Daniel R.  Milliard's spouse, as trustee for
Daniel R. Milliard's children.  In addition,  each member of the Limited
Purpose Group disclaims beneficial ownership of the  shares of Class A and
Class B Common Stock directly held by other members of the  Limited Purpose
Group or into which the shares of Class B Common Stock directly  held by the
other members of the Limited Purpose Group are convertible.

        Each member of the Limited Purpose Group, as well as Dorellenic, is a
party  to a Stockholders' Agreement wherein they agreed that so long as they
are the  holders and beneficial owners in the aggregate of not less than 25% of
the combined voting power of the issued and outstanding Common Stock, they
shall vote  their shares of Common Stock for the election of the directors
designated by a  majority of the voting power of the shares of Common Stock
owned by them as a  group.  "Common Stock" is defined in the Stockholders'
Agreement to include the  Class A Common Stock and the Class B Common Stock and
any class or series of any  class of capital stock into which such shares shall
be converted, and any other  class or series of any class of capital stock of
Issuer which has voting power  of any nature.  Accordingly, the members of the
Limited Purpose Group are acting  as a group only with respect to voting for
the election of directors and not for  the purpose of acquiring, disposing or
otherwise voting such securities.

        Since John J. Rigas has a majority of the voting power of the shares of 
Common Stock owned collectively by the Limited Purpose Group, he has the right 
by agreement to direct the vote of the shares held by the other members of the 
Limited Purpose Group but only with respect to the election of directors, and
he  has the right to consent to a sale of such shares by other members of the 
Limited Purpose Group.

                              (AMENDMENT NO. 4)

	The right of a party to the Stockholders' Agreement to dispose of
shares of  Common Stock listed in Item 5(b) and this Schedule C, in the absence
of the  consent of the holders of a majority of the voting power of the shares
of Common  Stock owned by the parties to the Stockholders' Agreement as a
group, generally  is subject to the pro rata right of first refusal of the
other parties to the  Stockholders' Agreement in the event of a contemplated
Public Sale (as defined  in the Stockholders' Agreement) and to a right of
first refusal in the Company  and the other parties to the Stockholders'
Agreement in the event of a  contemplated Private Sale (as defined in the
Stockholders' Agreement) of any  shares of Common Stock by any party thereto. 
The Stockholders' Agreement also  mandates in certain circumstances that a
decedent stockholder's estate offer to  sell shares of Common Stock in such
estate to the other surviving stockholders.

	Neither Dorellenic nor Highland is included in the Schedule 13D Filings
or  this Amendment No. 4 as a member of the Limited Purpose Group since their 
respective share ownership is set forth as being beneficially owned by each of 
its general partners who are themselves members of the Limited Purpose Group
and  are reporting such ownership hereby.

	Each of John J. Rigas, Michael J. Rigas, Timothy J. Rigas and James P. 
Rigas (the "Sellers") is a party to the Proxy Agreement with Ionian, which
gives  each of the Sellers voting rights over certain of the 940,000 shares of
Class A  Common Stock held by Ionian and certain rights of first refusal over
all such  shares.  Accordingly, shares held by Ionian over which each Seller
has voting  rights are reported as shares as to which such person shares voting
rights with  Ionian and each Seller reports shared dispositive power over the
shares held by  Ionian pursuant to the right of first refusal and the
requirement of Sellers'  consent to any other sale by Ionian.  The Limited
Purpose Group reports shared  voting power over the shares held by Ionian.

	John J. Rigas, Michael J. Rigas, Timothy J. Rigas and James P. Rigas
are  shareholders, directors and officers of Eleni Acquisition, Inc., the
general  partner of Doris, which is the general partner of SHHH.  As such, they
share  voting and investment control over the 1,458,151 shares of Class A
Common Stock  held by SHHH.  Accordingly, the shares held by SHHH are reported
as shares as to  which such individuals and the Limited Purpose Group share
voting power.

	LIMITED PURPOSE GROUP MEMBERS AND INDIVIDUAL REPORTING PERSONS.  John
J.  Rigas, Michael J. Rigas, Timothy J. Rigas, James P. Rigas, Ellen K. Rigas
and  Daniel R. Milliard are deemed to beneficially own 12,664,908, 8,688,774, 
8,688,774, 7,924,238, 4,747,815 and 4,375,453 shares, respectively, of the 
Class A Common Stock of the Company, each of which amounts includes (except for 
those accorded to Daniel R. Milliard) 97,949 of the same shares of Class A 
Common Stock beneficially owned by Dorellenic, a general partnership in which 
the above-named individuals (except Daniel R. Milliard) are the sole general 
partners and 4,374,453 of the same shares beneficially owned by Highland, a 
general partnership in which all such individuals are the sole general
partners.   In addition, John J. Rigas has the right by agreement to direct the
vote for the  election of directors of an additional 4,966,540 shares of the
Class A Common  Stock beneficially owned by the other members of the Limited
Purpose Group
