I am considering the purchase of Appletv. Here are my bonehead questions, and thanks in advance for any answers provided. What resolution are movies purchased off of iTunes at? Now on Apple's site, apple tv is stated to support 1080i. My hdtv is a few years old and only supports 480i/480p/1080i. No 720p for me. So will content thats 720p be scaled to 1080i (a la xbox 360) or scaled down (a la ps3) 480p? Thanks!
