AppleTV no longer appearing in iTunes. Suggestions?
I have a new AppleTV connected to my TV via HDMI. Everything was up and running just fine, I had over 100 gigs of music synced up to it, and then, after the latest iTunes 7.3 upgrade, it stopped recognising the device.
I have tried everything at this point, short of completely reinstalling the OS.
Closed & reopened iTunes, check.
Reinstall iTunes, check.
Restart computer, check.
Reboot router, check.
Try a different router, check.
Force DHCP release & renew, check.
Restore ATV to factory spec, check.
Pick new iTunes library, check.
Turn on port forwarding for UDP 5353, etc., check.
Place computer in DMZ, turn off all anti-virus & firewalls, check.
It just never shows up.
ATV gets on my network just fine, I can watch YouTube videos & movie trailers without a hitch, I've tried resyncing to a new iTunes library, etc., it simply doesn't work.
The only thing that has changed is iTunes, and since I cannot find an older copy, I can't try an older version to see if it appears in iTunes prior to 7.3.2 again.
Any suggestions? I am simply out of ideas and have spent hours trying to figure this out. I'm at the point where I'm about to either defenestrate it or sell it on eBay.
