But its very slow.


First of all, make sure you use at least growisofs 5.11. 5.11 addresses
DVD+ performance problem with Pioneer unit, but later it became apparent
that Plextor unit would exhibit same performance degradation. If you
already use 5.11 or later, then I can only tell that I've had received
report from another PX-708A user, who reported that recording goes with
varying velocity and significantly slower than expected. Reportedly the
problem just disappeared with kernel upgrade [from 2.4.18 to 2.4.22 in
his case]. The [subtle scheduling] problem is most likely IDE chipset
specific, as there are more reports that the unit performs as expected.

I checked and am running growisofs v5.13. So I downloaded and compiled kernel 2.4.23 (released over the weekend). And as you say the problem just dissapeared. As you say - probably an IDE chipset thing. So now I can report full x8 speed with the PX-708A and Verbatim disks (the disks say x4 but the drive runs them at x8).

How can I support growisofs and related things.  Developers need hard-
ware and beer last time I checked.
