Is it possible to play (mirror?) iTunes U videos straight to the newest Apple TV? I've not used airplay before, nor have I had an Apple TV. Currently on a roku and I use the "play on roku" thing a lot for music so I think I'd enjoy expanding the sources by getting an Apple TV. However, I wanted to make sure it was possible to airplay iTunes U videos from my phone to the Apple TV since I don't really ever use my laptop or iTunes, so I need it to work from my phone and not require desktop iTunes. Thanks!! Just want to make SURE the thing can do what I want before I buy it. Because the roku is fine for streaming everything else.
