MXL means Maxell, right? Note that Maxell DVD-R brand was exposed to
counterfeit attempt, see
http://www.maxell.co.jp/e/release/20030704.html. How does your emballage
look like?

Normally "Write Performance" appears in one of the "Speed Descriptor#N"
as well. The fact that it doesn't means that unit failed to properly
identify the media...

3/02/00 stands for "NO SEEK COMPLETE" (see
http://fy.chalmers.se/~appro/linux/DVD+RW/keys.txt for transcripts),
which just bizarre in this context and therefore most likely indicates
poor firmware support for this media. Well, given that Maxell is
well-established brand, it also might be as simple as media defect on
that particular disk... Did you try several disks or just one?

Well, it's hardly growisofs fault. As mentioned above, unit apparently
gets speed settings backwards. I would strongly recommend to try another
media brand. A.
