OK, I must admit I shouted out a little early, I´m leaving for a
holiday now so my mind is elsewhere;)
I´m using a simple QC with "Image with movie" and a "Billboard",
but the little BIG difference is that I´m using SMILE as a playlist
and that probably gives me the jitter/lag.
Of course, the SMILE doc plays excellent in QP and it follows the
most simple structure and no tags not supported by QuickTime.
