I have a problem where video stutters every second or two. The playback will freeze, audio continues to play, and then the video will unfreeze to sync with the audio. It always fixes when I reboot the computer, but only for a few days. Then it returns. Simply logging out and back in does not fix the problem.

The biggest clue, it seems, is that the stuttering does not occur if I click on the player window and move the window around. It plays just fine while I'm doing that, but the moment I stop moving the window, even with the mouse button still held down, the problem returns.

It happens with all video players, including Quicktime player and VLC.
It happens in all 5 logins.
It happens with all video file types.
It happens reading from both my internal drives and my external firewire drive.
I have 21 gigs free on my 160 gig HD. Even when I freed up more space it didn't help.

TechTool reports no problems with any subsystem (video, memory, etc.). I tried swapping RAM and even buying new RAM and still the problem occurs.

I tried repairing permissions and checking the drive for errors.

I tried removing plugins from
• /Library/QuickTime
• /Library/Internet Plug-ins
• ~/Library/QuickTime

I've spent hours trying to find a solution to this problem. Is is absolutely driving me batty! If you have any suggestions please let me know.

(I've posted this twice on the Apple Discussions forum and got nowhere, so maybe you guys can suggest something else to try)

Thanks for any help.
