growisofs - can't burn a dvd+rw

Hi,

i can't burn a dvd+rw with growisofs, here my command in telnet;

growisofs -dvd-compat -use-the-force-luke -Z /dev/sr0=/media/hdd/movie/__ts2dvd/_temp/Todesstille.iso

i got this error;

Executing 'builtin_dd if=Todesstille.iso of=/dev/sr0 obs=32k seek=0'
:-( unable to O_EXCL /dev/sr0: someone was in time to remount?

so i had a look in internet about this error and found that;

http://www.linuxquestions.org/questions/linux-software-2/problem-with-growisofs-596398/

but here the /dev/sr0 isn't mounted with fstab it's automounted or ?

how can i solve that problem ?

dvd+r is ok i can burn it.

regards

Biki3
