Just started using the new Apple TV 2 and have some questions. 1. If I buy a movie on iTunes on my MBP, then delete the movie, can I redownload it for free like I can with iPhone apps? 2. If I buy a movie on iTunes on my MBP, then delete the movie, can I play it on my Apple TV 2 without my MBP? (go to that movie in iTunes and click 'buy' or something?") From what I've been gathering, the Apple TV 2 can only play purchased iTunes movies if they are streamed from my MBP. Yet, I can rent an iTunes movie on my ATV2 and stream it directly from some iTunes server to my ATV2? Is this correct? Very confused!
