Quicktime playback problems - Mpg4 (h.264/aac) out of sync only in QT

I'm having some trouble with Mpg4 playback in Quicktime for windows. All my videos play fine in QT on a mac, they play fine in VLC on PC. But playback on QT for windows goes in and out of sync. It doesn't matter what Mpg4 codec I use, it happens with all of them.

I've tried uninstalling itunes as I had read that could create this problem, but that didn't fix it. I tried adjusting the audio output device latency because I read this could effect the sync as well. The only way we've found to fix this is to bring the file into final cut, take the original file out of sync by 3-10 frames and export with the adjusted audio. But I can't do this for every video, I have thousands and thousands of files for distribution. I need some solution for the player. Has anyone else encountered this problem and found a way to fix it?
