I have 3 ATV3's. I have a 2tb passport hdd and airport express router (small house, I get good/fast service thru it). As I understand it, I need a Mac mini running iTunes (24/7) to transport rip files from hdd to the router via Ethernet, which I can access wirelessly on my ATV's. True? The mini wouldn't really be "playing" the movie, just as a transport for the files from hdd to router over wired Ethernet, true? What's the minimum model # / hardware requirement for this task? I want to use Mac mini because I will be using a MacBook air to rip the movies. I do not want to use the MacBook for playback. I'm looking for seamless/Netflix style access to my movie rips thru the ATV. I want no interaction with the mini. Thanks you for any help and advice!!! 🙂
