Ok. I know this is probably a really dumb question, but messing with iMovie '09 has got me wondering. I created a movie in iMovie and went to Share----->Export Movie. The little box that popped up gave me five options to export to: Tiny, Small, Medium, Large, and HD. And to the right, it gave me the devices each export option would play on, and the Apple TV didn't have the option for HD. Can this be? If I create a movie in HD with iMovie, can it not really play on the Apple TV? I'm fairly close to purchasing an Apple TV, but this would be a real turn off. Thanks in advance!
