About 3 weeks ago our DVR started losing the programs that were being recorded during the day. I have lost all of the Christmas movies that I have recorded. It is so frustrating. I would check the DVR file and see that the movies were there but the next day they would be gone. Then I would delete programs from the DVR that I no longer wanted and would delete them from the trash file but they would show back up the next day after the system rebooted (or updated) during the night.
rdpalmer, Have you gotten any error messages on any recordings? Are you able to unplug the receiver for 10 seconds and plug back into the wall outlet? Does anything change?
