It depend about producer of your drive, if new firmware will support DVD-R/RW. In company´s PC i have NEC burner too, and have not problem with any types of disks. I upgraded firmware yet. In home PC i use LG multidrive burner and it has no problems too and supports DVD-RAM recording too. I think only LG supports recording and playing all DVD formats (mine LightScribe function too)
