Hello, I recently purchased a PX-716UF, and I use Windows XP Pro. My problem is that I can’t choose to burn dvds in 16X speed even if I wanted to. I used the Plextools Pro, and nero Infotool, and I can’t choose 16X for some reason. All I see is 8X and lower speed. I used Memorex 8X dVD+R, and HP 8x DVD-R. I use Nero Express for burning dvds and it also seems to think that max speed for my 716UF is 8X. How do I fix this?
