Over the past two months I have been having some issues with my DVR. The first instance, my DVR randomly rebooted as if it was getting an update and then continued to do that for a long time. It lost its recordings and lost the ability to record. I left it unplugged overnight and once I plugged it back in, everything worked fine for weeks. Then later on it did the random reboot again and leaving it unplugged brought it back to normal. Yesterday, it rebooted twice within a few hours. So far, I have lost all my series recordings and programmed series. Is there a way to restore the DVR to factory default? I don't know what to do at this point. Nothing I am trying seems to fix the problem. The DVR has lost a lot of functionality at the moment: I cannot pause, rewind, fast forward live TV anymore. No series records(it attempts to and fails then tries again and fails once more, leaving me with two recordings that are a few seconds each). As a result, the dual tuner does not really work. Do I need this replaced or can something be done?
