I've been having problems with my iTunes library dropping out of both my apple tvs. I've narrowed the problem down to my bt home hub 3. I've read a couple of posts which advise you to change the wireless channels. I've changed the channel to every option and none seem to work......the best channel I've found is 2, however after a couple of hours it still manages to drop out. Has anybody got any advice as to what i should do next? I can't find any further help.
