While watching a DVR recording, it suddenly stops and switches to a regular live TV program. I go back into my DVR recording and it picks up and then shortly suddenly stops and again switches to another live TV station.
Boy, if that dosen't sound like a bad DVR, nothing does.
The only thing that you can do is unplug for a few minutes to reset.
If that does not help, swap it for another.
You will lose your recordings.
Hi o5steinmeier, this does sound like a bad DVR, if after you powercycle the box and still having issues like barbie123 said, Please let me know and I can get one shipped to you or you can go to the local comcast center and swap it out there.
