last month I recorded eight 20 minute cartoons for my daughter. When finalizing the D-VR4SU it had an error. Since I have made 2 DVD's and finalized them with no problem. Yesterday after dubbing from the VHS to the DVD, I finalized the DVD-R and after finalization was complete I tried to play the DVD and the munu on the DVD was the play list from when the DVD had the error 1 month ago, and the DVD was blank except for that menu. I tried finalizing 3 DVD-R's since and it does the same thing each time. I lose the data that was recorded and am left with the menu from a month ago.
