Seriously, every video I see has some sound/video sync issues. I tried both Safari and Firefox since sometimes some video has issues on one browser. Both browsers exhibit the same problem. I know this is NOT a problem on my Xbox 360. Everything works fine and perfectly in sync. However, stretching 480p to 1080p on my TV is crap. I would rather just watch the lower res stuff on my Mac. My connection is not the problem either with this. It works fine on my Xbox 360 and I have a 16down/2up Mbps connection which should be enough to watch anything on Netflix. I have no idea what to do. All I can think of is that Silverlight is crap. Anyone here with the same problem?
