Thank you for the suggestions.

I updated my Lite-On firmware to the latest and tried ImgBurn.
Interesting, ImgBurn gave me the option to burn at 4x, but when I did
it started at 5.8x and went up to 6.1x.

Both Nero and ImgBurn show 2.4, 4, 6, 8 and 16x without a disk. I'm
using TDK printable disks the IFOInfo shows will burn at 6x and 8x.
DVDIdentifier shows the same disk writeable at 1,2.4,4,6-8. Shouldn't
I be able to force the write to 2x or 4x?
