I am looking for a 1-4 to 1-7 range DVD duplicator that will let me change booktype on DVD+R discs to DVD-ROM.

Some of the duplicators I have speced are based on single unit NEC players (2500as) on which I know the fimware can be hacked to change booktype.

Is it possible to modify the firmware on multiple unit dupicators to do this?

TIA.
