Hello peeps! I have a Late 2008 Unibody MacBook Pro. I love it, it's great. I upgraded to a 500gb HD and 4GB of RAM. Since I purchased it, Flash videos (Vimeo, YouTube, etc..) are jerkey in both Safari (3.0 and 4.0) and in Firefox (3.0 and 3.5). I've tried updating my Flash player, and just nothing seems to work. The audio plays fine, but the video stutters almost every few seconds. My video settings are on "Best Performance". Does this happen to anyone else? I'm just getting fed up. Thanks!
