So I have a mac mini running plex in my office and a 2TB lacie connected to my AEBS with all of my media able to stream to my various devices. My wifes little brother is getting us an ATV2 for christmas for my home theater and I am not sure if it will integrate into the system easily or if it will be more trouble than its worth. I have all of my music in my itunes library but my movies have been ripped and encoded with handbrake and I think most of it is in H.264 but I am not sure. itunes does not recognize the moves but I have never really tried to. Plex has all of the cover art and titles synced and works perfectly. I know you can jailbrake ATV2 but I am not really into the entire JB and basic code to make ATV compatible with PLEX.
