i am not saying your wrong I'm just questioning why they want to force the phone issue on dual tuners and not singels? its not like a dvr fee its got something to do with audits and verifying where the receiver is. or at least that's my guess. by stacking duel's its even cheaper and hides how many TVs you are actually using. when i ordered the VIP622 they asked me specifically where in the house it would be and if a second TV would be hooked up to it and where that TVs location is. they said i must notify them if i move eather connection. this if i remember is something directv does label the boxes to a certain location.
My thoughts exactly, "don't make sense" but "does make cents"
I don't think I had all of those questions, but am suspecting that they were building a database on you to understand where everything is in case they needed to help you, in the unlikely event you did not know something.
Also, when I had DirecTV here not long ago, DirecTV wanted to know where each receiver was so that they could disable the correct receiver when they sent you out a replacement. You would not have to give them the serial number or any of the other numbers associated with the box.
EDIT: Easier to say the receiver in the Living Room, Bedroom 1, Bedroom 2, Barn, or maybe at the neighbors house.
