Hi! I'm thinking about getting an iPad 2, and I've heard that you can now play files from Computer to iPad using Airplay, is this correct? If so, I have a few questions: - Is it limited to iTunes purchase only? I've encoded alot of my DVDs to mp4 format, so i'm hoping I can play them without them filling the iPad up. - Do Videos show up in the Video interface with album art and such? Thanks.
