The BookType setting is a "must" for all latest model burners released on the market today.

The drive, in the bundled version with Nero 6, has by default the BookType set to Automatic and can be changed to DVD-ROM. So we inserted DVD+R, DVD+R DL and DVD+RW media and changed the Booktype for each. In the case of DVD+RW media, we witnessed that the booktype change was not recognised on all drives. We also noticed that the bitsetting was only possible on brand new DVD+RW discs. If the disc had been previously used, the bitsetting could not be set, despite Nero reporting that the disc's booktype setting had indeed been changed to DVD-ROM.
