[Bug 1356528] Re: k3b dvd burning crashes with growisofs and -use-the-force-luke=dao: option

Hi,

thanks for your detailed answer. And yes, you're right, I should wait 
until the burning process has finished ;-)

Here are the last few lines output:

What do you think, is this a drive issue like you mentioned before or 
something else? I found some bug reports with similar errors.

btw, I found a dvd+r double layer disc in my working desk and tried this 
one. Besides dummy write has not worked and I've wasted a double layer 
disc for about 200 MByte of data, everything went fine.

The not working disc is a dvd-r type.

Thanks,

Jan.
