<i>I've never quite understood why the resistance to the various Ogg formats?</i><p>My guess is that because there's no support for Digital Restrictions Management.  Apple has already widely deployed software and devices that can play restricted h.264, and that's what the media companies that produce the content "want".  (Of course, I never watch "media-company content" on Youtube.  I doubt anyone whose videos I watch on Youtube would want Restriction Management on their files.)<p>Incidentally, all of the music I've bought recently has been in FLAC format.  Seems like everyone I listen to offers it in addition to mp3s.<p>(It's just video-producers that think I am going to pay them $2 for a TV show I can't watch on my portable device.  Haha, fat chance.)
