Again I thank you for your ideas. I think we are beating a dead

the LG GSA H42LI drive. It too says it can read RAM at 12x. It
read at 3.5Mb/s which is 3x. It is 50% faster than the Pioneer.

I have no problems reading from DVD-R with the Pioneer or any of the
other drives. That isn't my focus, however.

My motherboard is the EVGA 680i SLI with an NVIDIA chip set. The problem
isn't in my machine as the differences among the various brands of
drive evidence.

There you go, you are seeing exactly what I see. Only the BenQ drive
lives up to what is written on the box. The BenQ does read at 5x.
I got the BenQ on sale at Staples over a year ago for $20. The
model is no longer available.

I use the same cable as with the BenQ. You can't get udma4 unless you
have a 80 wire cable.

Burning isn't the problem, but I use cdrecord for -R disks
and growisofs for +R. I don't write to RAM with the computer.

I use the IDE/ATAPI driver in kernel 2.6.20.
