Is there any book type SW for NECs?

There is a neato prog for my Lite-ON to change the book type of DVDs to the more compatable CD-ROM type. Is there anything similar for NEC drives ?

Welcome to the forum.
CD-Speed and Binflash can change booktype on NEC drives but you need a firmware that supports Bitsetting for +R/RW (this is not supported in original NEC firmware).
You should be able to find everything you need here.
