I have posted in another thread that I have got an order placed for the 622 this morning with a 2/21 install date. During the order process when we got down to discussing an installation time I was asked if this 622 would be replacing my current 811. I told him no it would be in addition. He told me that would not be possible for me to have both. He said this promotion was only available if I did the install as a replacement. He didn't say anything about wanting my 811 back, but he did say that I could only have one HD receiver in my house. I even made him repeat it. I don't' know what the reason why was and he could not explain it to me. My first thought was they just didn't want to run new wires. But don't know. Anyone heard of this or can explain???
