Hi Gürkan, The problem happens in the growisofs call. Have you tried using the same command as the one at the bottom of the log to burn the DVD directly using growisofs ?
If that command doesn't work, I would try without the "--use-the-force-luke" and the "--speed" parameters. Also, I don't believe that this problem happens in the testing and unstable versions of K3b, so installing one of these might be another option for you. Francois
