CT, you have learned the biggest lesson of using the forum. you posted that you don't have splitters and you have rebooted the DVR. Now back to your question. Yesterday I was unable to get the higher channels to work but the lower ones were fine. I rebooted the box but that didn't help. a few hours later, the higher channels started working. I hope you get lucky. I have called several times for explanations of error codes, but the answers were always vague. I don't think the 3.1.1.2 means much. if your problem continues, you might need to swap DVR's. it is free to swap.
