Bad Backups

[Crank]

I just bought a Sports pack Dreamcast for my sons birthday and I am unable to get backups to work. It was manufactured in July 2000. I'm using NERO and the burns are reported as successsfull. My burner won't work with disc juggler. I am thinking of getting a new Lite-on 24x burner. I guess what I'm asking is how can I tell if its my burns or the Dreamcast. The burns are readable in Win Explorer...but only the audio tracks. The bottom of the disc looks like a sectored GDROM.

Thanks!
