                                 AMENDMENT NO. 1

                                 TO SCHEDULE 13D

         This amended statement on Schedule 13D/A (this "Statement") amends the
Statement on Schedule 13D originally filed jointly by Liberty Media Corporation
("Liberty" or the "Reporting Person") and Ascent Entertainment Group, Inc., a
Delaware corporation and indirect, wholly owned subsidiary of Liberty ("Ascent")
with the Securities and Exchange Commission on April 7, 2000 (the "Original
Statement"), and relates to the common stock, $0.01 par value per share (the
"Common Stock"), of On Command Corporation, a Delaware corporation (the
"Issuer"). Items 2, 3, 4, 5, 6 and 7 of the Original Statement are hereby
amended as set forth below. The Reporting Person is filing this Statement as a
result of certain transactions by Ascent which have increased the percentage of
outstanding Common Stock the Reporting Person beneficially owns (the "Shares").

ITEM 2.  IDENTITY AND BACKGROUND

         Item 2 is amended and supplemented by adding the following information
thereto:

         "The reporting person is Liberty Media Corporation whose principal
business address is 12300 Liberty Boulevard, Englewood, Colorado 80112.

         The Reporting Person succeeded to its initial beneficial ownership of
Common Stock in connection with the merger (the "Merger") of Italy Merger Corp.,
a wholly owned subsidiary of AT&T Corp. ("AT&T"), with and into
Tele-Communications, Inc. ("TCI"). TCI, as the corporate parent entity of the
Reporting Person, had previously filed a Report on Schedule 13D reporting
beneficial ownership of the Shares. On August 10, 2001, AT&T effected a
split-off of the Reporting Person and as a result of that transaction, Liberty
is no longer a subsidiary of AT&T.

         The Reporting Person owns interests in a broad range of video
programming, broadband distribution, interactive technology services and
communications businesses. The Reporting Person and its affiliated companies
operate in the United States, Europe, South America and Asia with some of the
world's most recognized and respected brands, including Encore, STARZ!,
Discovery, USA, QVC, Court TV and Sprint PCS.

         Schedule 1 attached to this Statement contains the following
information concerning each director, executive officer or controlling person of
the Reporting Person: (i) name and residence or business address, (ii) principal
occupation or employment, and (iii) the name, principal business and address of
any corporation or other organization in which such employment is conducted.
Schedule 1 is incorporated herein by reference.

         To the knowledge of the Reporting Person, each of the persons named on
Schedule 1 (the "Schedule 1 Persons") is a United States citizen, except for
David J.A. Flowers, who is a Canadian citizen. During the last five years,
neither the Reporting Person nor any of the Schedule 1 Persons

                                        3




(to the knowledge of the Reporting Person) has been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors). During the
last five years, neither the Reporting Person nor any of the Schedule 1 Persons
(to the knowledge of the Reporting Person) has been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and,
as a result of such proceeding, is or was subject to a judgment, decree or final
order enjoining future violations of, or prohibiting or mandating activities
subject to, federal or state securities laws or finding any violation with
respect to such laws."

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         Item 3 is amended and supplemented by adding the following information
thereto:

         "Ascent entered into a Stock Purchase Agreement (the "Stock Purchase
Agreement"), dated as of April 25, 2001, with Jerome H. Kern and Mary Rossick
Kern ("Sellers"), providing for, among other things, the acquisition (the "Kern
Acquisition") by Ascent of 2,245,155 shares of Common Stock (the "Kern Shares").
The Kern Acquisition was consummated on May 1, 2001. Ascent paid aggregate cash
consideration for the Kern Shares in the amount of $25,200,000, a portion of
which was paid directly to Sellers and the balance of which was paid to The Bank
of New York to retire certain indebtedness of Jerome H. Kern to The Bank of New
York. In connection with such payment to the Bank of New York, Liberty was
released from its obligations under its guarantee of Jerome H. Kern's
indebtedness to The Bank of New York. The purchase price for the Kern Shares was
paid from Ascent's available cash.

         The foregoing summary of the terms of the Kern Acquisition is qualified
in its entirety by reference to the full text of the Stock Purchase Agreement
which is included as Exhibit 7(j) to this Statement and is incorporated in this
Statement by reference.

ITEM 4.  PURPOSE OF TRANSACTION

         Item 4 is amended and supplemented by adding the following information
thereto:

         "The purpose of the Kern Acquisition was to allow the Reporting Person
to increase its beneficial ownership of the Issuer. Except as otherwise
described in Item 6, neither the Reporting Person nor, to the best of its
knowledge, any of its executive officers, directors or controlling persons, have
any present plans or proposals which relate to or would result in: (i) any
acquisition by any person of additional securities of the Issuer, or any
disposition of securities of the Issuer; (ii) any extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Issuer or any of its subsidiaries; (iii) any sale or transfer of a material
amount of assets of the Issuer or any of its subsidiaries; (iv) any change in
the present board of directors or management of the Issuer, including any plans
or proposals to change the number or term of directors or to fill any existing
vacancies on the board; (v) any material change in the present capitalization or
dividend policy of the Issuer; (vi) any other material change in the Issuer's
business or corporate structure; (vii) any changes in the Issuer's charter,
by-laws, or other instruments corresponding thereto or other

                                        4



actions which may impede the acquisition of control of the Issuer by any person;
(viii) any delisting from a national securities exchange or any loss of
authorization for quotation in an inter-dealer quotation system of a registered
national securities association of a class of securities of the Issuer; (ix) any
termination of registration pursuant to Section 12(g)(4) of the Exchange Act of
a class of equity securities of the Issuer; or (x) any action similar to any of
those enumerated above.

         Notwithstanding the foregoing, the Reporting Person may determine to
change its intentions with respect to the Issuer at any time in the future. In
reaching any conclusion as to its future course of action, the Reporting Person
will take into consideration various factors, such as the Issuer's business and
prospects, other developments concerning the Issuer, other business
opportunities available to the Reporting Person, developments with respect to
the business of the Reporting Person, and general economic and stock market
conditions, including, but not limited to, the market price of the Common Stock
of the Issuer. The Reporting Person reserves the right, depending on other
relevant factors, to acquire additional shares of the Common Stock of the Issuer
in open market or privately negotiated transactions, to dispose of all or a
portion of its holdings of shares of the Common Stock of the Issuer or to change
its intention with respect to any or all of the matters referred to in this
Item."

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         Item 5 is amended and supplemented by adding the following information
thereto:

         "(a) After giving effect to the Kern Acquisition, Liberty beneficially
owns 20,528,197 shares of Common Stock through its subsidiaries. Based on the
30,866,327 shares of Common Stock that were issued and outstanding as of
November 19, 2001 (as disclosed in the Issuer's Definitive Proxy Statement filed
on November 29, 2001), the 20,528,197 shares beneficially owned by the Reporting
Person represented on that date, on a pro forma basis calculated in accordance
with Rule 13d-3 of the Exchange Act, 64.2% of the issued and outstanding shares
of Common Stock. Of the 20,528,197 shares beneficially owned by the Reporting
Person, (i) 19,404,365 of those shares are Common Stock, (ii) 1,123,792 of those
shares are represented by immediately exercisable Series A Warrants, and (iii)
40 of those shares are represented by immediately exercisable Series B Warrants.

         To the knowledge of the Reporting Person as of the date of this
Statement, none of the Schedule 1 Persons beneficially owns any shares of Common
Stock, except for (i) Jerome H. Kern, who beneficially owns 1,350,000 shares of
Common Stock (assuming the conversion of 13,500 shares of Series A Preferred
Stock held by Mr. Kern), (ii) Paul A. Gould, who beneficially owns 13,300 shares
of Common Stock (12,500 of which are issuable upon the exercise of options to
acquire the same), (iii) Gary S. Howard, who beneficially owns 13,300 shares of
Common Stock (12,500 of which are issuable upon the exercise of options to
acquire the same) and (iv) Elizabeth M. Markowski who owns 25,000 shares of
Common Stock (20,000 of which are restricted).


                                        5




         (b) Liberty has the sole power to vote or to direct the voting of the
Shares and the sole power to dispose of, or to direct the disposition of, the
Shares.

         (c) Except as set forth in this Statement, no transactions in the
shares of Common Stock have been effected by the Reporting Person and, to the
knowledge of the Reporting Person, the only transaction in the shares of Common
Stock effected by any of the Schedule 1 Persons was the issuance of 800 shares
of Common Stock to Paul A. Gould on February 4, 2002, in consideration of his
services as a director of the Issuer in 2000 and 2001. Gary S. Howard is
entitled to receive 800 shares of Common Stock in consideration of his services
as a director of the Issuer in 2000 and 2001, but those shares have not yet been
issued.

         (d)      None.

         (e)      Not applicable."

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

         Item 6 is amended and supplemented by adding the following information
thereto:

         "A wholly-owned subsidiary of the Reporting Person has entered into a
Purchase Agreement, dated as of August 16, 2001, with Liberty Satellite &
Technology, Inc. ("LSAT") (as amended, the "Purchase Agreement"), pursuant to
which LSAT will acquire all of the shares of Ascent indirectly owned by the
Reporting Person. The transaction is subject to the approval of LSAT's
stockholders at a meeting scheduled to be held on March 26, 2002. If the
transaction were to be consummated, LSAT would be a beneficial owner of the
Shares and other securities of the Issuer held by the Reporting Person (other
than 125 shares of Common Stock and Series B Warrants to acquire 40 shares of
Common Stock, the beneficial ownership of which would not be transferred to LSAT
in the transaction) and would share voting and dispositive power over such
securities with its parent, the Reporting Person.

         Ascent entered into a Preferred Stock Purchase Agreement (the
"Preferred Stock Purchase Agreement) dated June 29, 2001, with the Issuer,
providing for the acquisition by Ascent of an aggregate of 60,000 shares of
Cumulative Convertible Redeemable Preferred Stock, Series D of the Issuer (the
"Series D Preferred Stock"). Pursuant to the Preferred Stock Purchase Agreement,
on each of June 29, 2001, August 2, 2001 and October 18, 2001, Ascent purchased
20,000 shares of Series D Preferred Stock at a purchase price of $1,000 per
share, or an aggregate of $20,000,000.

         Pursuant to the terms of the Certificate of Designations for the Series
D Preferred Stock (the "Certificate of Designations"), the shares of Series D
Preferred Stock are convertible on and after December 31, 2002, at the option of
the holder, into Common Stock at the initial conversion rate of 132.4503 shares
of Common Stock for each share of Series D Preferred Stock. The conversion rate

                                        6




is subject to adjustment upon the occurrence of certain events specified in the
Certificate of Designations.

         The foregoing description of the terms of the proposed transaction with
LSAT is qualified in its entirety by reference to the text of (i) the Purchase
Agreement, a copy of which has been incorporated by reference as Exhibit 7(g),
(ii) the First Amendment to Purchase Agreement, a copy of which has been
incorporated by reference as Exhibit 7(h), and (iii) the Second Amendment to
Purchase Agreement, a copy of which has been incorporated by reference as
Exhibit 7(i). The foregoing summary of certain of the terms of the Preferred
Stock Purchase Agreement is qualified in its entirety by reference to the text
of the Preferred Stock Purchase Agreement, which is included as Exhibit 7(k) to
this Statement and is incorporated in this Statement by reference."
