You are right, quicktimes in VLC (even in OSX for me) play fine! It looks like reverting back to an older quicktime is the solution but honestly I’m afraid to do it. (my boss is not a video guy, and i would get stomped if something went wrong….) Is it an easy thing to do??
I found Larry Jordan’s site that had the warning, then when i stared searching for quicktime 7.5 studders and chopping there is a TON of people having problems. Those little kicks are a perfect description of the playback problem. And its random!
