Hello.

Sometimes burning a DVD fails, with output of something like this:

Executing 'builtin_dd if=/dev/mapper/dm-bild1-dvd of=/dev/brenner obs=32k seek=0'
/dev/brenner: restarting DVD+RW format...
/dev/brenner: "Current Write Speed" is 4.1x1385KBps.

But growisofs nonetheless returns with exit code zero. Scripts won't detect
the error. This can lead to data loss, when they assume that the data has been
burned successfully.
