While Nero is burning the movie file to the disc after transcoding the file it will eject the disc with this statement "Disc is not empty. Please insert an empty disc (the disc i used was brand new) You will not need to transcode again if you cancel the recording now, unless you change the project data afterwards" I've put in a new disc and it ejects it and when I cancel it aborts the burn. What does all of this mean?????
