It have 1.06 firmware (flashed yesterday, before I used 1.04) and it's
alone as a secondary master. I can't check hardware revision because I'm
in different part of city now.

And if you let the unit do 8.0x, the result is good?

Interesting. Have you ruled out a posibility of defective unit?
Can you try it in other, preferably Windows, box? Can you try with
cdrecord-ProDVD? What does "atacontrol mode X" reports? (X is 0 or 1
depending on the channel you have unit connected to).

In fact, the GAH is a very powerful and secretive organization whose
single weakness is its lack of existance.
