LOS ANGELES -- Video of the 12-round fight between Oscar De La Hoya and Floyd Mayweather Jr. was taken down from YouTube.com on Monday after HBO filed a copyright claim, the Los Angeles Times reported on its Web site.
HBO had exclusive rights to rebroadcast the pay-per-view fight Saturday. However, the original broadcast was available on the Internet site during the weekend.
One video appeared to have come from a poor-quality, foreign-language broadcast, while another was a relatively high-quality copy that included announcer Jim Lampley's call and the post-fight decision that went to Mayweather, according to the Times.
The videos were taken down shortly after 4 p.m. Monday and replaced with a notice saying it was "no longer available due to a copyright claim by Home Box Office Inc."
An e-mail seeking comment from a YouTube spokesperson was not immediately returned.
"We take our copyright issues very seriously," Ray Stallone, spokesman for HBO, a division of Time Warner Inc., told the newspaper. "We consider it extremely valuable programming, and we reacted quickly when we saw that it was available."
The first video drew several thousand hits; the higher quality one had a few hundred hits per round, the Times reported.
Also available online was footage of the Kentucky Derby, which aired Saturday on NBC. A network spokesman said YouTube was not authorized to show the race in which Street Sense rallied from 19th place to win.
