I just bought a plextor 716a and when I burn my DVD's the speed for burn is only at 8x. I have a slow computer, a p3 800mhz processor. Would that be the cause or the 8x speed and not the 16x. And yes I choose max for burn speed. Or is it because I use 8x dvd, verbatium Also when analysis it reads at 1.3x. Is that the normal or is the computer again.
