I have been trying to get my itunes connected to play on an apple tv but it is neither showing up in itunes nor is my computer showing up on the appletv. I checked to make sure bonjour service was working and restarted the appletv and all that jazz. in addition my computer is showing up in my roommates itunes when i turn on library-sharing. Firewall was turned off as well to see if that did anything. Anyone else having issues sharing things over the networks?
