Advertisements I have a cable box, vcr and tivo hooked to my tv. I am trying to install RCA D930 signal senders so that I can watch all my premium channels in another room. I have it hooked up through the cable box, but I am having trouble changing channels in room #2. Should I hook it up through the tivo? If I do where would I put the base unit to the signal sender? I am using the ir cable to change channels on the tivo. Thanks for any help!
