For some reason, my external Sony DVD Driver(DRX-830U) can read CD-R and DVD's. It can burn CD-R but can't seem to burn game images to DVD's. I have alot of burning software like Nero, Alcohol 120%. Recently i updated my firmware. I used Sony's DVD+R to burn some images to DVD's and started out okay. After like 2 days, it won't burn anymore on Sony DVD's. Also I tried other DVD brands like Maxwell DVD+R and it worked out fine. Should I get DVD-R? Does Anyone know whats the problem with my DVD driver?
