I have a motorola HD Dvr box that seems to have recording capabilities. I have had the box for a few years and have never tried to record on it. I decided that I wanted to try it so tried to record Homeland. When I pressed the button the red dot came up signaling the show was to be recorded. However when I try to got to list to replay it I get a message saying that the DVR service is not available or has been disabled. What do I need to do to fix that.
