I can't figure out what's wrong. Whenever I use clone dvd after any dvd I always have to burn 2 disk. The first time I always get an error about the media. After I replace that disk with a new one it burns fine. It's almost like it has to do a practice disk first then it burns. This happens on every movie. Any clues? I have updated my drive GSA-H21N from Dell and the disk I use are verbatim. So what gives???
