I recently started having issues watching video of any sort on my MBP. I have a 13" MBP from early 2010 with the 2.26 Core 2 Duo processor and 4 GB DDR3 RAM. Video playback is starting to stutter, no matter what video I'm watching. The audio is fine, but the video struggles. I am running 10.6.8, and have updated Flash player to 10.3 to try and resolve the issue to no avail. Even videos shot on my iPhone played back through Quicktime in iPhoto stutter. I can't watch videos through iTunes either because of this stutter issue. Anyone else have this issue and been able to resolve it? The videos used to play back with out any problem what so ever. The video starts out fine, then hangs for about 3 seconds while the audio continues, then the video goes into a super speed until it catches back up.
