I currently have a Dish 625 (2 room DVR SD) and an older receiver (1 room, not DVR, SD). I am planning on replacing the old receiver with a ViP 622 for 2 rooms, leaving me with a total of 2 receivers for 4 rooms (one HD). A customer service representative told me that it would cost $100 for installation and the ViP 622 receiver. Is it possible that I would need a new receiver for the HD receiver, and if so would that be included in the $100 receiver/installation price? If it isn't included how much do you think it will cost for a new dish? Thanks for the help.
