After thinking about it for awhile i bought a apple tv today and i'm already starting to regret it. I can't get the thing to sync with Itunes. I've tried it wirelessly, hardwired, straight in, etc and each time it say some error to do with port 3689. I don't use a firewall and don't think it is a router as it wouldn't sync even when connected straight to the apple tv box itself bypassing all other network elements. I can stream to it just fine, it's the syncing that is causing all my issues. any ideas?
