Does anyone know a way around the iDVD problem where, as the film progresses (usually happens by the 40-50 minute mark) the audio gets a fraction of a second ahead of the video? My main use for the program is to make DVD's of my band's live performances. It's pretty frustrating to watch a gig where eventually the drummer's sticks are hitting the drums after you hear them. I was hoping it would be fixed by now (problem has been around forever and I've submitted lots of feedback about it) but I just burned one with 4.0.1 and it's still there.
