I just installed a new ATV2 to my Imac. I am streaming wirelessly via a router. All music and photos from my Imac are showing up on the ATV2 under computers. I can browse and rent tv shows and movies from the store as well. Netflix set up worked fine and Youtube works fine. What seems to be missing is the entire "Music" section which would allow me to browse music and videos similar to what I can do for movies and tv shows. Once again, music from my Imac shows up in the Computer section but there is no "Music" tab to see music from the store. The only oddity I see in the setup is that the ATV2 is not showing up as a device in Itunes, like my orginal ATV did. It doesn't appear to be a firewall issues since the tv and movies is coming up but I am by no means a network/firewall expert. Did anyone else have this issue and/or have any things to check? thank you.
