Microsoft denies Windows Media blocks digital broadcasts

Microsoft says that there isn't anything in Windows Vista Media Center that would have stopped Vista users from recording two NBC Universal shows earlier this month. On May 12, people who attempted to use Windows Vista Media Center to digitally record NBC Universal shows American Gladiator and Medium received a message saying the copyright holder had blocked recording of the shows. NBC Universal later acknowledged that it accidentally sent a flag to prevent recording. What upset many Vista users is that the block couldn't have been carried out unless Windows adhered to the flag. Microsoft said that it honors flags sent to protect against the recording of "premium content" from pay-per-view channels or video on demand (VOD). The company said that it doesn't prevent the recording of over-the-air digital or QAM digital broadcasts. What Microsoft didn't say was how, if Windows Media only honors flags intended for analog broadcasts, were users stopped from recording digital broadcasts.
