I have been intermittently receiving the "Complete signal loss" message for about the last 2 weeks and it's not weather related. The strange part is that when the message appears and I push the DVR button on the remote, I get a perfectly clear picture of the station I am on in the upper right hand corner of the initial DVR screen. If I hit cancel to leave the DVR screen, the complete signal loss is still there. I explained the problem to DN service and the rep advised that it may be caused by a corrupted DVR recording and to try deleting my recordings one at a time to see if that corrects the problem. I was wondering if anybody had heard of this as being a fix for this type problem.
