The BookType setting feature is a "must", which all the latest models released on the market should be equipped with. Until now, NEC with its previous models has supported this feature only for the DVD+R DL format. Hopefully, this has been changed with the 4550 and the 4551 burners. The ND-4551A can change the booktype to DVD-ROM for DVD+R, DVD+RW and DVD+R DL formats.

The drive by default is set to DVD-ROM for all media. With the contribution of some helpful utilities, you can change the booktype. Below you can see some screenshots from DVDInfoPro software and Nero CD/DVD Speed. Both can be used to change the default booktype setting of the ND-4551A.

Even with Nero Burning Rom, you can set the booktype for the discs you are about to burn.
