Apple TV does not show up in iTunes
Suddenly I can no longer find Apple TV in my devices in iTunes. I have even gone to extreems by resetting my Apple TV (first generation) to factory settings, blowing away anything that I had originally stored on it. No way can I get it to show up so that I can pair my desktop and Apple TV. I use to be able to do this but all of a sudden no more. I have an airport so I was doing this wirelessly. Now, no icon for Apple TV apears in devices in iTunes. I can sync my iPhone and iPad, they show up. Any advice would be greatly appreciated.
Thanks for your help!
