A:AnswerYou should have an HD DirecTV box; if so, then Insignia should come up in the setup screen. If not, call DirecTV and ask for programming. You can also purchase a universal remote.
A:AnswerYou might be better off with a HDhomerun Prime. You can watch/record 3 channels at a time and use a roku/Apple TV (with Channels app) as a front end on any TV you want.
