I've had some problems with some movie files running QTP 6.0.2 on 9.2.2, including the commercials on Apple's web site, where the sound just keeps skipping, and only plays about .3 seconds every 4 seconds or so. I don't know if upgrading to 6.2 will help or not, though it says the installer package can't be found when I try to use Quicktime Updater.
