My r15 just reset by itself. Just before resetting the picture goes black but the audio is still going and the record light comes on. I try to change the channel using the remote and on the box, no responce from either. Sometimes when a self reset occures, the screen with the Directv logo appears after a few seconds. Sometimes I have press the reset button on the box. It does this at random and has been doing it for a few months. I think the box is starting to reach the end. I don't mind cause I've had the box sence 06. And the random resets on the r15 are the only problems I have had with all of my units.
