I have a few movies in iTunes that are 1080p I knot the Apple TV doesn't output 1080p, but it can still play the 1080p content and output it at 720p ( I think many of us know this now) That being said, I've been watching one of thos movies, and it did pretty good for about half of it... I could notice the framerate isn't the best. But now the appletv is restaring and or giving me an error message. And the apple tv is really hot. I think it's over heating an now can't handle the comely at all. Keeps crashing. So it looks like the a4 can't handle 1080p content for too long. Really to bad, but I guess that's why it's only suppose to be 720p right now.
