I had an 811/510 and 310 installed at the beginning of Sept. (swictched from cable). Didn't know if dvr for HD would be worth it, but once I started using the dvr on my non-hd set, I was hooked. My installer told me if I wanted to get a 921, I'd just plug it into the spot where the 811 is (in basement). Went to local store yest, salesman confirmed, just plug it in and so I brought it home and did so, then called Dish to activate it. No picture, just a banner would appear and it said it couldn't lock onto a satellite. 
Called back, and only now I'm told (after I mentioned it) that it needs two feeds (input one and two) and that I have to run another cable from my switch (in the attic) to the basement (three stories!).
Is this right? We used the existing cabling to hook everything up the first time, and there is only one cable that runs down to the basement. Help!
