Quicktime audio/video out of sync

Hi there,

I have some problems with the Quicktime output in After Effects, the audio is out of sync by a couple of frames every time, no matter what quicktime format I choose, it even happens with Animation. Uncompressed avi is perfectly synced...My comp just contains a lot of psd's and wav's, nothing weird going on with that.

I've already searched around a bit for this but there doesn't seem to be an answer, but isn't this a MAJOR problem? What do you guys do to be able to export to quicktime properly?
