When I pause a video (on any streaming sites or iTunes) midway, then return to it some time later by clicking the playback arrow, the video will not continue from where it's left off. It just freezes. But this happens intermittently. Sometimes it freezes sometimes it doesn't. The only sure workaround is to drag the circle in the time bar forward/backward to 'wake' it up. But I can not get it to start from exactly where it's left off. It's really annoying. I have tried reinstalling OS X 10.6 but that didn't help. My MBP is currently running 10.6.7, 2.4GHz Intel Core 2 Duo with 4 GB of memory. I would be eternally grateful for any help. Thank you!
