Hey there. I just bought a 180-hr Series 2 DT. This is my first Tivo. I get basic cable at home with all the normal channels I need. I also get one International channel on Dish Network. In the welcome setup I managed to easily configure the cable however I can't do dish network. Again I only need one channel so I don't need to use the IR blasters... it keeps asking me if it successfully changed channels so I just said yes or otherwise I can't move forward. Will the tivo ever try to tune to a different channel by itself on the dish (it can't cuz the ir blasters aren't hooked up)? I know it gets all the movie trailers or whatnot from a certain channel but will it get it from cable or from dish?
