Have been trying to burn a track to CD-R using Media Player or Nero. Although everythings fine when burning to CD-RW, when I use a CD-R, Media Player fails to burn completely and Nero says burning is successful but trying to play track in CD player gets no response - computer asks for disc to be inserted. Have I got to change any settings for a successful burn to CD-R (40x)? What could be wrong beacause the CD player itself and the CD rewriter are fine. Thanks for any ideas.
