I currently have 3 tv's in main residence, a vip 722 & vip 612. Also 1 tv at secondary residence w/ vip 612 on separate dish but 1 account for both places costing just an extra hd receiver. Is this the best set up? I am at secondary frequently while wife is at main residence. Thinking about upgrading to Hopper 3 but believe would sacrifice the secondary dvr to qualify. Any downside at secondary?
