I have a RDR-DC200. It has previously frozen whilst downloading from the HD to DVD. Last night it froze whilst trying to delete a "jumping" recoded program. I have to unplug it from the mains to be able to restart it. it now won't turn on. I am waiting to see if it reverts back to it's pre-programed recording (it did this previously). Has anyone else had this problem and, if so what did you do about it?
