I just received an Apple TV 2 as a gift, and I dont know which one to go with. I am a Mac junkie, but when it comes to these video conversions, I am really novice. I do really know what to do at all. All I want to do is stream stuff wirelessly from my iMac to all my devices. I am currently just streaming music from my itunes to my Apple TV. I just downloaded iVi to try and convert all my MKVs, but am not really sure what to do next. Anyways...knowing how f'd up I am currently, which one should I go with?
