I have NEC6500A DVD drive in Dell 700m laptop. Just flashed the fireware to 2.24(liggy). I am trying to use DVDinfo to change the booktype from DVD+R to DVD-ROM so that the DVD I burned can be read by my 5 year old DVD player. I managed to change the booktype for both default and temporary settings in the Bitsetting menu. But after I burned a DVD, I checked the booktype, it is still DVD+R, so my old player can't read it.
As a new user of DVD pro, please excuse me for my silly question, how can I change the booktype with DVDinforPro (Ver4.21). I use Ridata DVD+R. Thanks in advance!
