Set up the Apple tv box. Everything appeared fine, tried most things and they worked (airplay from pad, you tube etc etc) Tried the music sharing from the pc and it worked fine. Went back on later and it will not now play music from my i tunes library via the "computer" selection which shows in the menu. This selection normally brings up all the available i tunes stuff (music, videos) on my pc. When I click on that selection I get a message saying I need to turn on home sharing on the pc inside the I tunes programme, but it is turned on? Anybody have any idea what I am doing wrong? I am working purely with wi-fi connection by the way. The annoying thing is it was working? Would an ethernet connection be better?
