I moved into my house and it had the 3 LNB original HD dish. I tested with a my old room mate's (whom didn't move with me) equipment and had 2 D TiVo's working fine with all 4 cables. I setup an installation as a new customer through Best Buy to get the the HD receive and $350 in Best Buy rebates. I got an HD DVR and a standard def receiver, with the intention of using the gift cards to get another reciever. They cut off 3 of the coax lines and installed SWM, but only configured the DVR for a single tuner. Later I figured out what was up and reconfigured it. I was initially disappointed because I was planning on adding two DTiVo's to my account, but got over it because I want to go 100% HD. I then bought a 2nd DVR from Best Buy (HR22 with a manufacture date in lat e November?) and went around and around with activations, because they neglected to flag my account. I wasn't seeing 5 birds because I have the SL3-S dish. At least I don't have to use the BBCs.
