i'm using an external dvd-recoder (liteOn SOHW-832S), and have a lot of
troubles buring DVDs (cds aren't any problem)

./growisofs -dvd-compat -Z /dev/sr0=/data/tmp/sicherung.iso
Executing 'builtin_dd if=/data/tmp/sicherung.iso of=/dev/sr0 obs=32k seek=0'
:-( unable to umount /dev/sr0: Unknown error 141

can anybody tell me, what this error-message means?

big thx,
roman
