Well I do believe there may a glitch in the firmware and I will PM Dee 27 and see what she says.
I did discover that for the DVD+ R\W bitsetting to work a new disk must be used, an old one won't work, this was in the FAQ's that came in the formware download.
Note you can only change booktype on a new unused +RW media. Changing booktype can not be performed on a used +RW disc.
[font=Verdana]I went out and bougt some new DVD+ R\W. Figuring perhaps it was maybe a glitch with the Sony media in the firmware, the RichohJPNW11, so I bought FujiFilm Media.[/font]
[font='Times New Roman']To my disappointment it was also the RichohJPNW11.[/font]
I reflashed the drive again, rebooted, then checked all the bitset setiings in CD speed and they all displayed DVD-Rom for all + media.
I burn a movie and it's perfect, booktype displays it burned in DVD-Rom.
I then erase the disk in the NEC 3540 and now the booktype shows DVD+ again.
Figuring it needs to be burned to get back the DVD-Rom format I do another burn and it failed to burn at Rom, once again the disk only displays DVD+.
I am at my wits end with this. I took that same disk put it in CD speed and did a quick format using my Liteon burner, final result was the disk was once again DVD-Rom.
It appears the firmware is not holding the bitsetting for DVD+ R\W, it does work for the DVD+ SL media. It seems it will only work once on a brand new disk, erase it and the disk will never burn -Rom again.
