I have Driver HL-DT-ST DVDRRW GWA-4164B On my Nero Program the following Recorders show up: Image Recorder (DVD) Image Recorder CD-R/RW HL-DT-ST DVD RRW GWA 4164B DVD HL-DT-ST DVD RRW GWA 4164B CR-R/RW I can not make a Data DVD, either DVD+R or DVD-R. I am able to make a CD-R or CD-R/W. I was told that DVD's have a greater capacity and have bought many DVD+R and DVD-R to find out that they do not work. When I burn these DVD's with Nero Express I get a window asking to insert the disc to be written on: Disk Requirements: DVD+R/RW, DVD-R/RW, DVD+R9, Double Layer. When I insertet a DVR+R the burn session failed at 16.620KB's. When I put a DVR-R in the CD-ROM the shute opens to eject the disk.
