SCHEDULE 13D/A

Amendment No. 5

Statement of

LIBERTY MEDIA CORPORATION

Pursuant to Section 13(d) of the Securities Exchange Act of 1934

in respect of

ACTV, INC.

Liberty Media Corporation, a Delaware corporation (the “Reporting Person” or “Liberty”), hereby amends and supplements its Statement on Schedule 13D filed on March 29, 1999, as amended on October 28, 1999, July 13, 2000, May 29, 2002 and October 10, 2002 (collectively, the “Original Statement”), with respect to shares of Common Stock, par value $0.10 per share (“ACTV Common Stock”), of ACTV, Inc., a Delaware corporation (the “Issuer” or “ACTV”). This amendment (this “Amendment”) constitutes the Final Amendment to the Original Statement. Capitalized terms used but not otherwise defined in this Amendment shall have the respective meanings ascribed thereto in the Original Statement.

Item 2. Identity and Background

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

Schedule 1 attached to this Amendment amends and restates Schedule 1 as filed with the Original Statement and contains the following information concerning each director, executive officer and 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.

Each person listed on Schedule 1 (collectively, 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 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 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 4. Purpose of Transaction.

Item 4 of the Original Statement is hereby amended and supplemented by adding the following:

As previously reported, on September 26, 2002, OpenTV Corp. (“OpenTV”) and ACTV entered into an Agreement and Plan of Merger (the “ACTV Merger Agreement”) providing for the acquisition by OpenTV of ACTV in exchange for Class A ordinary shares of OpenTV. On July 1, 2003, pursuant to the ACTV Merger Agreement, as amended, a wholly owned subsidiary of OpenTV merged (the “Merger”) with ACTV and ACTV became a wholly owned subsidiary of OpenTV. As a result of the Merger, each outstanding share of ACTV Common Stock as of July 1, 2003, was converted into the right to receive .73333 of a Class A ordinary share.

As a result of the Merger, the ACTV Common Stock is no longer listed for trading on a national securities exchange or quoted in an inter-dealer quotation system of a registered national securities association. ACTV has filed a Form 15 removing the ACTV Common Stock from registration under the Securities Exchange Act of 1934, as amended.
