Has anybody used Playback with an Xbox 360 core and Mac Mini? Any drawbacks? I'm trying get some of my Mac Mini content from the living room to the bedroom. So far, seems like the cheapest way. Need it to be easy for my gf to use too. I have a Mac Mini (early 09), Xbox 360 core (w media remote), Airport Express (g/b) or Madcatz Network Adapter (n) for the Xbox.
