I have Apple TV 2.0, I was watching a movie which was being streamed from my desktop computer. Towards the end it would no longer stream and now I do not see Apple TV in the devices under iTunes. iTunes will not recognize the apple tv. When I go under itunes preferences I have it look for apple TV's and mine is listed, I can connect to the network with the apple TV, but itunes is no longer connected and it doesn't showup on my desktop. Is this a apple tv problem or a itunes problem????
