Hi Dan,
Thanks for the patch.  You're a star! The one that's doing the work is almost 
certainly just the first.   However, the second won't hurt either ;-).

Since the first patch really only changes the sequence header prog_seq bit 
the desync bug will probably only show on some decoders. If the decoder turns 
off pulldown based on this bit  and the frame rate (wrong!) it will lose 
sync.  If it relies instead on the frame headers (correct!) it will work.   
That's probably why it hasn't shown up earlier...

cheers,

        Andrew
