How does the dvr work with only one coax? If you want to record Jim Rome is Burning, does the TV display that show or can you watch something else? Can you still pause live TV? I tried to run another RG6 to the location where my TV is now, but I can't get there. My ceiling is vaulted and I cannot fit all the way back to where I need to be in order to run the second cable. My wife is not into the drill a hole through the wall thing, so that is out. Any ideas? Thanks.
