I tried streaming a movie last night from my computer to my Apple TV. The movie is about 2.3 gb, and it couldn't handle it. The movie was incredibly jerky if it was even playing at all (also tried a bigger file, but obviously it was worse). The only way I got it to work was to downsize it to about 1.5 GB, but then it had horrible artifacts everywhere. Is it not possible to stream a movie from a computer in decent quality (was just 1080p and 5.1 sound)?
