Hi there, I'm confronted to a problem I can't seem able to solve: when I play a youtube/dailymotion video in full screen, the audio will gradually lose synchronisation. After 30 secs, the out of sync is clear, and if I click pause, the images will continue playing behind the pause symbol for a very short moment. My flash is up to date (version 11,4,402,287), and Firefox too (version 16.0.2). What should I check? It's getting boring to be unable to watch any videos in full screen... My system: Mac OS X, 10.6.8, 2.66 GHz Intel Core 2 Duo, 4 GB Memory. Thanks a lot if anybody can help me!
