Is it possible for the new Apple TV to work with an existing iTunes install syncing with the last generation Apple TV? I ask because iTunes on my iMac refuses to show up on the new Apple TV. It is able to see my MacBook Pro library just fine on the same network, but that laptop has never been synced with the last generation Apple TV. The iMac continues to work just fine with the old Apple TV, syncing new content. Here are some of the things I have tried to make this work: - Rebooted all computers/routers/network equipment. - I have tried wiping the router and reconnecting devices from scratch. - No firewall is setup on the iMac. The MacBook Pro can see the iMac iTunes library just fine on the same network. - Both Apple TVs have their own unique local IP address. - I have tested a different router with all devices connected. - I have attempted to connect the new Apple TV to iMac iTunes by turning the old one off downstairs. No difference. The iMac still refuses to appear on Computers menu. Is there some compatibility issue here that prevents an existing iTunes library currently syncing to last generation Apple, from working with the new Apple TV when you connect it to the network? I have googled all afternoon for solutions but I'm not having much luck. Usually you find at least some others experiencing a problem if it's a common issue. So the fact nobody else is blogging or posting about this on forums (as far as I can tell) concerns me this is a weird glitch related to my own setup. Any ideas?
