Thanks guys. This weekend I'm going to try swapping the receivers, but I've been looking around and think its time to upgrade everything to hopper.
My account has 3 VIP receivers on it. 1 622 in the garage on its own 1000 antenna, and the 622 and 722 on the house 1000 antenna. As I understand it I have to upgrade all 3 to hoppers as dish won't allow old VIPs on the same account with hoppers. So do I have to replace all three receivers simultaneously and then call to remove the VIPs and activate the hoppers? I'm going to wait to add joeys for some extra TVs later.
