If charlie had misspoke about MPEG-4 channels, wouldn't he have been told to correct it before the end of the show? Surely someone is listening to him...
Usually if charlie is unsure he asks someone else to clarify or at least confirm, one of the hooligans behind the camera, so if he didn't do that I'd say what he said could have a little something behind it. I realize it's been a very busy month for them and things have obviously changed, and could change again, but if they made changes because of suggestions made then they know we're watching and hanging on every word. I can't believe they enjoy the email barrage when they say something untrue...
December 22nd is the next big date for HD info, mark it on the calendar...
