[MacDV] Losing audio sync in iMovie/iDVD

[Brian Olesky]

Using iMovie 4.0.1, I recently built a 6-minute video made up of a series of
short, under a minute .dv files, with a few titles separating them into
sections. However toward the end, the audio suddenly goes out of sync. It
happens right after a section with two iMovie-generated title scenes, one
after the other. Could that be the problem? Is there some way in iMovie to
correct the sync? When I preview the "problem clips" in the timeline,
they're perfectly in sync. They just go out when the whole video is played.
(And when it's burned to a disc with iDVD4.)

TIA
