A few questions about watching movies on the new iPad... I looked on iTunes for Donnie Darko and it was available. It didn't say what resolution the movie was in but it did say it was also available for the iPad and Apple TV. When you buy a movie on iTunes, and download it to one of your devices, does it scale it to the device... or do you chose which resolution you want to purchase the movie at? Also, I have tons of digital copies that have come with movies... I have a stack of them. Will they all convert to iTunes or are there only certain ones that are compatible with iTunes? Thanks.
