I'm surprised there hasn't been more follow-up on this! Someone has a working ATV 4th gen and more people aren't asking questions about it and there don't seem to be any answers coming. The main questions seem to be about people's own media - does Siri search through them (especially if people have added meta-data to their rips) and are TV shows organised in a better way? Both of which I'm interested in knowing the answers to. If Siri can only search through the various 'shops' then it's not much good to me.
