yep, so the background: no kde, no gnome, my own filemanager (which
can't handle mounts, just files :-)), no distribution - all self
compiled (oops, not 100%, e.g. OpenOffice) ..
no special supermount tools etc.

even after shuting down the autofs the error was there.

I also, because at home DMA was running all the time and suddenly
I had the same error there as well!?

Nevermind. Today I tried again at home with DVD-R and a new kernel
(2.4.24) and growisofs 5.16.4.8.5 and it runs.. but please don't
ask me to downgrade to reproduce the error ;-)

Nevertheless without given the speed arguement it reports
a speed of 2x but the media is 1x. According to the current
firmware of the drive the media should be handled.. But as
long as the result is fine I think I can ignore the STDOUT.

My next tests will be at my other setup in the company - also
with the new 2.4 kernel and the new growisofs. Let's see what
happens.

thx + cu
