When I first start up iTunes, I can choose a movie or TV Show from the AppleTV to play, but after ~20 minutes it loses connection and returns to the AppleTV's home screen. From there I can still see my library on the AppleTV, but it just spins when I choose something. Where it gets weird is is I can push the movie or TV show to the AppleTV without any issues. An entire movie can play without any issues. It was working correctly up until I updated iTunes to 11. I'd prefer to not have to downgrade iTunes as 11 significantly sped up my library. Having to get up after every 22 minute TV show to start the next one completely defeats the purpose of me buying the thing. I am running Windows 7 x64 with the latest version of iTunes and the latest software on ATV. Everything is wireless as Ethernet is not an option where the devices are located.
