my NEC DVD-RW-Drive ND3550A doesn't support changing of the Book Type to "DVD-ROM" for DVD+R / DVD+RW.
Several Tools (Binflash, Nero Info Tool, Media Code Speed Edit,..) report the following Firmware-Version:
_NEC DVD-RW ND3550A 1.52
At Liggys and Dees Web site is no Bitsetting-Firmware for Version 1.52 (http://liggydee.cdfreaks.com/page/de/NEC-ND-3550A/).
Is there another Version from this Web site, that should work ?
I dumped my 1.52-Firmware with Binflash, but couldn't attach the dump, because of the large filesize.
