I got a DVR earlier this year. It has been working fine but recently I have been experiencing some weird things. I have noticed that around the same time (10am, 3am) That the record button lights up. But I go to manage recordings and nothing is recording. Why does that happen? Also when these "invisible recordings" happen I get a message of "not enough space delete old recording or stop recording message. I also get that sometimes with my programmed recordings even though I clearly have 20% recording space. So what is wrong? Is the DVR defective? Or am I doing something wrong?
