I'm using firmware 1.02 and the manafacturer ID of the disk is PRODISC R04.
I have change the booktype in nero speed tool. I don't really understand if changing the booktype this way should help copying though.
It will not copy the disk OR the image to DVD +R.
Thanks for your help.
The Disk (image) only has over 2GB so no need to shrink and it is not copy protected.
