New Version 4.25 supporting bitsetting on DVD-R/RW media ist out:
Quote from changelog:
Upon a request from a CDFREAKS forum moderator I extended the bitsetting capability of NEC drives to add -R and -RW book types.
Sascha
This version does NOT support bitsetting on DVD-R/RW media, it only allows setting the booktype to DVD-R/RW on DVD+R/RW/R-DL discs. But that was really fast, considering that this functionality was added to Binflash on 2004/09/16 in version 0.95 - the first version including bitsetting at all. 
But I was not the one to request this feature since I don’t need this program at all 
Ditto.
I have no need for this application.
You can use this to look for b0rked firmwares and lazy firmware coders… for example, Plextor drives refuse to read DVD+R that is set to DVD-RW

Bad lies.
