sorry i know this is talked about on here but i couldn't find a simple answer. i have a 722 that was feeding hd in the living room and sd to the bedroom. well that sd tv crapped out and im getting a new hd lcd. so what would it cost to add a second hd dvr for the bedroom? or can i have 2 dual tuner hd dvrs? i have the 1000 dish. ive only been a customer for a few months, and i signed a 18 month contract. thanks a ton for any help.
