my Panasonic DMR ES10 will record from the comcast DVR recording but will fail at finalizing. I tried different DVD +R, Different speeds from 4x to 16 x and DVD -R. One thing seems to work. If I play the DVR from the cable box and pause the playback before it is completed, I then stop the recording on the Panasonic and can finalize sometimes. The finalization process makes a very bad scatchy sound before it tells me it failed. Any ideas?
