I have a Direct TV DVR R15 (NOT TIVO), Magnavox MWR10D6 DVD Recorder and a GE Television without audio/video input jacks so I have a RF modulator. I have connected the DVR, DVD Recorder, and the television but when I turn both on at the same time and try to burn a show to DVD or record a show to DVD the picture becomes unwatchable/scrambled. I can play a DVD on the DVD Recorder by itself without the DVR on and I can watch the DVR without the DVD Recorder. Does anyone know what the problem is?
