Continuous channel issues like the one you are describing are usually related to the signal and require a field technician to investigate. If you have not already scheduled a service call, then one is recommended. This would require a tech on site and cannot be addressed remotely. Please let us know if the issue continues after a service call is completed.
Technician was out today and said incoming signal was strong. He checked outside where cable enters the house and all was good there. He came back in and plugged in the power cord to the DVR and everything was back to normal. He said something in the DVR is not receiving the nightly signal in the problem will probably return the next day. He offered to replace the DVR with another but I didn’t want to lose some treasured recordings. I plan on recording some of those onto DVD and if the problem continues I will exchange the DVR.
Just for the sake of asking the question...you don't unplug or otherwise disconnect your DVR at night do you?
