I've been using for a long time DVD + R DVDs from different manufacturers for my home videos. My already older DVD players've never had a problem. With these Sony DVD + R, the video is not recognized by the DVD player. On PC and other DVD players run. Is it now the DVD player, the DVD writer or to the DVDs. I have copied the videos on TDK DVD-R. We behold - my "treasures" they can play again. The advice of a Saturn employee "DVD-R make less problems". For me, this Sony DVDs are useless.
