I've wasted 3 disks already. K3b stops burning at ~ 50% with the error "mkisofs
crashed".

DVD writer - NEC ND-3540A
DVD disk - ACME DVD+R 2 layers, 2.4x
Burn options: default

According to http://support.necam.com/optical/ND3540A_specs.asp this DVD writer
supports DL disks.

k3b doesn't burn DVD DL because it use bad parameter for growisofs (who
work well from shell)

In the image error.png attached there is another common problem: k3b
doesn't recognize the speed allowed (retrieved by dvd+rw-mediainfo, I
suppose) and it set a a speed who is always higher than the chosen value
(in some case limit I have saw things like 99x !)

Hello,

What's that parameter? You seem to have come far in debugging the problem but
forgot to tell the most important info :)

If the fix is trivial enough, the problem could still be solved in time for
squeeze.

Well, we need dvd+rw-mediainfo output then for that particular case.

Nevermind, the latter has already been fixed in 2.0.1 which has been in
unstable for >4 months already. See

I think it is the parameter -dvd-compat, it's a safe option for DVD5 but
breaks at 50%  of the write for a DVD9

But i have not debugged k3b, I have done some tests burning with
growisofs from shell and with or without the -dvd-compat option.
