Intermittent Loss of Local Channels and Searching for Satellite Message

[musicilove67]

I have an older model DirecTV DVR receiver in my living room. After watching my local channels for a few seconds or minutes the signal is lost and I get a "searching for satellite 1 (or 2)" message. I can click away from the local channels for half-an-hour or so and go back to them and again the same thing happens. This is a new problem(I use to get local channels with no problem). Interestingly, I get good reception of my local channels with another regular receiver in the bedroom. Also, when I move this bedroom receiver out to the living room, I get the local channels on it with no problem. Is this a connection problem or a DVR receiver problem?

Thanks!
