Hi folks. I want to move an old DirecTV DVR to a bedroom and connect it to my DirecTV dish (which has dual LNBs). The DVR is capable of receving two inputs, but I only have one existing cable coming out the wall in this bedroom (left over from my original dish which only had one LNB). Is there a way to "split" this signal from the one coax cable to the two DVR inputs? I don't think a traditional diplexer or multiswitch will do it, but I am treading on unfamiliar territory. Do I have to run another cable or is there another way to do this? Any help would be appreciated! Thanks.
