I want to move all the content on our AppleTV back to the main system library attached to our iMac and after turning off streaming, I can't find any way to sync the Mac with the ATV. The only way that I can find to make the ATV show up in iTunes' device list is to start them go to Settings > Computers > Add A Shared iTunes Library from the ATV menus, but that just put puts us back into streaming mode. I can't find a way to get the ATV to show up in the iTunes device list and then set up syncing. HELP!!!!!!!
