I'm having problems with the audio sync in Imovie. I've had no problems before using my old Jvc handycam. I'm now using the canon 5dmk 2. The clips are .mov format H.264, 16bit, 48khz, MPeg 4 compression. It runs fine when played in Imovie. The problem is when I either export to a quicktime movie or try to burn with Idvd. The movie runs fine for about up to 10 minutes, then after that, the audio on the clips also has audio from the other clips layered over the top. I've already extracted the audio onto a separate track, as before it was much worse, the audio just stopped halfway through the movie, and was if the audio was running faster than the images.

Any help would be really appreciated. I'm just stabbing in the dark.
