Just curious if anyone else here has it working. I just bought two new Apple TVs. They are on the same wireless network as my Media PC, which is running the latest and greatest iTunes. Home Sharing is definitely turned on. My MacBook Air, also on the same wireless network, sees it just fine; I can browse media, play music, etc. Neither of my new Apple TVs sees the Home Share. When I click on "Computers" it just shows that "Turn On Home Sharing In iTunes" screen, as if I haven't turned it on. I've tried signing out and signing back in on both units, as well as on the Media PC...nothing.
