When you go into the setup menu of the DirecTivo unit, and go into the "Channels You Receive" list and punch in which channels you don't get...

If the power goes out, is that information lost? Or does it survive a power loss?

I'm not going to get into the side discussion of how irritating it is that I have to do this at all. The thing should just know which channels I get already, without me having to manually intervene and tell it which ones I don't get. And DirecTV changes their channel lineup every time the mood strikes them, so you have to go in and do it again..

Oh wait, I said I wasn't going to get into that discussion...
