Hello,
Not sure from your post whether the issue is with a Cox Cable DVR or an after market (Sony, Panasonic) DVR with the On-Screen TV Guide. If the former, a hard reset - unplug as Cox advised - should do the trick.
If it's the latter ... I had a similar problem with my Sony RDR-HX900 DVR. To fix it, I had to do the following. Made certain that the cable to my Sony DVR did not go through my Comcast cable box. Even though the Comcast box has an RF pass-through, it seemed to block the On-Screen TV Guide overnight update both to my Sony and to my Pioneer plasma TV. This will require a couple of extra cables and a splitter.
Second, periodically I have to unplug the Sony - another hard reset - then run through the set-up again. I've had the Sony for about 2 years and have had to do this 3 or 4 times. It may be the cable company makes changes to the signal that confuses the DVR, or maybe the DVR runs out of memory. Someone who knows more about this should weigh in.
I have no idea why this worked or why it's necessary, but it has and it is.
Hope this helps. Good luck.
Bob R.
