Apple TV plays iTunes songs at random
OK. So I'm navigating the options in AppleTV. I scroll over to "Computers" then down to "Settings". When I hit Computers, all of a sudden random songs from my iTunes music collection on my MAC! start playing over the stereo speakers, not the TV. (AppleTV isn't connected to the stereo.) For the life of me, I can't figure out why one should have anything to do with the other.
