I've tried home sharing on and off, signing in and out, turning on and off, resetting the unit etc. Nothing seems to work.
Anyone got any suggestions other than 'reset your apple tv'?
I looked through the list of things that you said you did and did not do. If, in fact, you had listed 'setting location' as one of the things you tried, the sarcasm would be deserved. Are we always to assume that people who ask for help on this forum may not have missed the obvious? I fail to see how such obnoxiousness will engender a helpful community.
So, a little maturity, if you please. Lest people think poorly of our country.
I had the exact same problem, but when I set the location to USA, I was able to access my Photostream, Youtube, Internet Radio and a whole bunch of silly man-games. I use the US itunes store because someone gifted me a bunch of iTunes Cards from the US to start me on this appdiction.
Apple TV gen 2, iOS 5.1 updated yesterday.
