My DMR-BWT800 has suddenly (in the last three days) stopped copying to DVD (archiving). What can have gone wrong? I put in a new DVD from the same stock as usual and press the blue (copy) button, as usual, and it goes back to the broadcast instead of the copy menu. What can have gone wrong? Any ideas? BTW, I am not pirating but I have a motorhome and we have no means of watching TV so I record films and watch them on the laptop on wet evenings away in the motorhome. Harry
