I know how to change a book-type to DVD-R, DVD+R and so on already but what I need is a DVD with a DVD-RAM book type and none of the programs I’ve tried so far offers this. If that would help, my burner is LG; I’m not sure what model exactly, it is listed as HL-DT-ST DVDRAM GSA-4167B in Nero Burning ROM.
Hi and Welcome!
the answer is simple: you can’t. Period.
The only defined book-typing is DVD+R, +RW and +R DL to DVD-ROM. Other booktype options do not exist.
