The TV tuner is rather interesting if like me you only have one antenna cable and not a TV Box. I plugged today, it works fine Xbox directly recognize the connection and proposes to set your Freeview channels For me the only downside is that Freeview HD channels are not available in primary choice. (For example, TF1 HD is # 51) What is normal but you can not change the order as on our TV What makes it rather unpleasant, because I also purchase the Xbox remote control in parallel (which incidentally is beautiful) but that does not "encrypted" buttons as a Lambda remote.
So use in the choice of channels and quite complicated. Fort Point -> With the SmartGlass applications -> Oneguide your tablet or smartphone, it allows you to watch streaming TV and even make pause..etc
Malgrès that, the TV tuner for Xbox One is a great product that I recommend for those who want to watch TV while playing.
