I'm sure this is a stupid question. I have one standard PVR in the basement connected to a TV. I had a second standard PVR but it died. I had heard that you can run one PVR on two tv's? I have two lines coming in to my basement. One for the good pvr and one for the dead. Can I just run a coax from the output of my pvr to my basement "media box" (where all my network and tv cables go to)which has an external output and will it work?
