ITEM 1. SECURITY AND ISSUER

     No Change.

ITEM 2. IDENTITY AND BACKGROUND

     As a result of the transactions disclosed in Item 4 relating to the
reporting person's withdrawal of securities from Magness Securities, LLC
("Magness LLC"), the reporting person now holds a 33% interest in Magness LLC.

     GMag, LLC is a Colorado limited liability company wholly-owned and managed
by the reporting person.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     On October 31, 2002 Liberty Media Corporation (the "Company") issued for
no additional consideration to each holder of its Series A and B Common
Stock, .04 subscription rights for each share of Common Stock held. Each
whole right ("Right") entitled its holder to purchase from the Company one
share of Series A Common Stock at a price of $6.00. The reporting person used
existing funds, available margin credit from Goldman Sachs and the Stanford
Group Company and funds generated from the sales of Series A Common Stock
described in Item 4 to exercise his Rights and acquire the underlying shares
of Series A Common Stock.

ITEM 4. PURPOSE OF TRANSACTION

     On October 10 and 11, 2002, the reporting person withdrew from Magness LLC
a total of 25% of the stockholdings of Magness LLC and placed these securities
in GMag, LLC. Since the reporting person and Kim Magness shared dispositive
power and Kim Magness, as manager of Magness LLC, had sole voting power over
shares held in Magness LLC, these transactions resulted in a change in the
reporting person's dispositive and voting powers. Since the reporting person had
previously reported his beneficial ownership in the securities held by Magness
LLC his overall beneficial ownership did not change as a result of this
transaction.

     On October 31, 2002, the Company issued to the reporting person
individually 102,335 Rights. In addition, the reporting person beneficially
received 20 Rights jointly with his wife, 16 Rights on behalf of his wife,
485 Rights on behalf of his daughter, 311,288 Rights as the sole member and
manager of GMag, LLC, 3,887,323 Rights as co-beneficiary of the Estate of Bob
Magness, 933,862 Rights as a member of Magness Securities, LLC ("Magness
LLC"), and 41,760 Rights as a member of Magness FT Investment Company, LLC
("FT LLC").

     On November 22, 2002 the Estate of Bob Magness sold 1,034,260 Rights. In
addition, the reporting person sold shares of Series A Common Stock as follows:



                                                              Shares of Series A     Consideration
                                                               Common Stock Sold        Received
