I am looking for the best deal for my father. He just got a new HD widescreen and wants to sign up for E*. He would like HD and DVR in the living room, and then something in 2 bedrooms. I noticed on the dishstore site, that he could get an 811 and a 625. It states you can upgrade to the 942 for $250. Is it possible to get setup with a 942 AND a 625? Or a 942 and any other dvr for the additional bedroom? Basically can you have DVR in 3 rooms?
