Lets just do some simple math rather than dig into the registry.

Alcohol burns 4 CD's at 8X (the true burn speed according to you) and it takes almost 12 minutes.

Nero burns 4 CD's in 3 minutes

12 minutes ÷ 3 minutes = 4 times
4 x 8X = 32X

So OK Nero has lied to me about the speed. It does not change the fact that 3 minutes is faster than 12 minutes on the same PC with the same media.

Alcohol obviously has a problem with multiple burners.

And still.... no one has answered the questions.
What's that tell ya?
So I'll ask the questions again....
Anyone out there burning to multiple drives?
How's it working for you?
