My ATV2 does not shows up in itunes. Home share works fine. I am also able to see my itunes in my TV thru ATV. Itune ver. 10.2.2. ATV2 ver 4.2.2. I have already tried those things that are stated in apple's site, like turn off ATV, Turn off router, log-off itunes, reinstall itunes, hardwire ATV to PC, etc. Also tried UDP port settings, firewall turn off/on, etc. No luck yet. Any help appreciated. Thanks.
