I'm wondering if the problem is entirely with iMovie itself. I experienced major video sync and overall system performance problems when I upgraded OS-X to 10.2.2 on iMac flat panel 800 mhz w/ 512k RAM. I was using FCP on a previously produced project to dub release prints. Several hundred copies later I discovered that lip sync near the tail of the program was way off and audio was stuttering badly. Had to reboot to Sys 9 and run FCP from there wherein the problem disappeared. Overall performance in OS-X 10.2.2 was so bad I ended up downgrading back to 10.2 and problems again disappeared. Couldn't understand why I wasn't seeing anyone else complaining about these major performance issues. Under 10.2.2 rebooting system several times a day would temporarily reduce performance problems. After a few weeks I got brave again and did the combo system update directly to 10.2.3 and now everything's working great again. In retrospect, the problems really didn't seem to be related to FCP itself, just the system's flaky performance. Can't comment in iMovie 3 issues since I don't use it, but since there is such a vast array of good and bad experience being reported here, I can't help wondering if it's system performance problems creeping into the mix.

Not to mention, probably the greatest love story ever put to film.
