Thanks for the reply coolsammy,
I can view my CDNV-80MT disks just fine on all computers. That's why I decided to have look at the CNDV-100MT's before I put them in the AVIC D1. I've read a lot about people winding up with "blank" screens after downloading off torrents and burning disks. I don't want that. I've written the vendor on ebay but haven't received a reply. I'll post what happened when I hear something, in the meantime the disks will stay on my desk.
