A while back, DirecTV came out and gave connected a second line so we could watch/record multiple shows. We are in the process of a basement refinish and I have only one working line until I can get the electrician to correct the problem with the second line. Right now, I can't watch anything from the guide and only some programs are recorded? Can I tell the receiver/DVR to only use one line for now or did they split the signal so I need both lines? I looked in setup and tried setting it back to Single Tuner but setup failed.
