Whenever I start QuickTime 10.0 player, videos that play skip frames every 5 seconds or so. Then I discovered that even when nothing is playing, everything on the computer skips. When I move the mouse around the curser skips. When I open other applications, they skip. When playing videos using Front Row, that skips as well. When I close QuickTime, the issue stops. When I use DVD player, video plays back perfect (without QuickTime open). I looked at the activity monitor and everything looks normal. I'm baffled. I seems like just the simple task of opening QuickTime 10 creates some sort of CPU pause or something. Any ideas?
