Hello! I bought an Apple TV 3, and so far it's working great. I can play my songs in it, using home sharing and clicking on "Computers -> Music". I can airplay everything, all my iDevices recognize that there is an Apple TV ready to receive youtube videos, etc. But there's one problem, I can't access my musics by clicking on "Musics" in Apple TV. It says that my library is empty and that I can use iTunes to sync. But on iTunes, my Apple TV never shows on my devices list. Everything is up to date, I even restored my Apple TV using my iTunes (connected using a USB cable), but my ATV 3 still doesn't show on my devices list in iTunes. Is there something that I can do to try and fix this? Thanks!
