The little birdies that clued us in about the upcoming Vista Media Center update a few days ago are at it again, but this time with some potential good news. When the recent Windows Media Center TV Pack release candidate 0 was released to testers and was missing all of our favorite features, we were quick to assume that this would mean no new features until Windows 7. Well, based on some recent information received by our sources, the reason H.264 was cut was because it was too complex to add -- because of all the dependencies involved -- in time. You see, evidently this tuner update was promised to be released to OEMs by the end of July. Now our sources seem to be optimistic that there is another update in the works, and that it might just include both H.264 and DirecTV tuner support. More about the Windows Media Center TV Pack after the jump.
