Excuse me, but has the ipod/iphone *ever* supported b-frames? As far
as I know, these devices only do Baseline which does not have b-frames
at all. I'm not aware of an ipod that can play Main or High profiles
with b-frames as only these profiles allow such frames

No clue on shitty Quicktime... Who cares for that crap? :p
