I am having problems recording certain non-copywrited DVDs from my Samsung player to my Panasonic DVD -R recorder. When the DVD I have just recorded is played back, a solid black line appears at the bottom of the screen, the rest of the picture is perfect. (It does not appear on the original DVD) I am connecting the Samsung via a scart to the TV and to the Panasonic via a scart to 3x phono lead. I have recorded other DVDs within the line appearing. Can anyone offer any advice
