There seems to be a difference between "dual layer" and "double layer." Reason I suspect this, is because I bought a Verbatim "Double Layer" 8.5GB DVD and copied the 9.2 Pro DVD onto it. Unforunately my normal DVD-ROM, and no other DVD-ROM I tried. It does work on a few DVD writers though.
Think of "double layer" or "double sided" as two separate disks, that just happen to share the same piece of plastic. A dual layer disk has twice the capacity available, without changing or flipping.
Could there be a difference between the layout of data on the disc between "double layer" and "dual layer" ? I know "double sided" - the disc I used definitely wasn't double sided. That's why I'm curious of what the difference between "double layer" and "dual layer" might be. My drive (LG 16x DVD-ROM) can read the original disc fine, but no the copied one. No other DVD-ROM I've tried it on would read the copied one. -- Kind regards Hans du Plooy SagacIT (Pty) Ltd hansdp at sagacit dot com
