Hi guys been checking this site out for some time now, ran into a problem... I did the NFL sunday ticket install and got a HD DVR(HR24-200), a HD Receiver (H24-200), and 2 SD Receivers (D12-100). When the tech did the install he said with the new setups the HD DVR only needed one cable coming in instead of two. I came across a SD DVR (R15-300) that I wanted to added to the computer room. When I plugged it in the first setup screen (searching for satellite signal) completes but the second screen (receive program info) never leaves 0%. Granted I haven't activated this receiver yet and not expecting to get channels just wanting to make sure its not a lame duck receiver. When I checked signal strength I was only getting hits on odd transponders. Tried a forced software update and never left 0%. Any suggestions? Do I still need to feed two cables in, even though my HD DVR only needs one?
