Hi,

today I tried to burn a video dvd for the first time. Two times I used k3b, which utilises growisofs. The third time I created the ISO image manually with makeisofs and called growisofs on the command line.

$ growisofs -dvd-compat -Z /dev/dvdrw2=mydvd.iso
Executing 'builtin_dd if=zeremonie.iso of=/dev/dvdrw2 obs=32k seek=0'
/dev/dvdrw2: "Current Write Speed" is 8.2x1352KBps.

I just want to note, that growisofs doesn't return after this error, and has to be killed. Still I can't eject the DVD from the drive.

I also find the aforementioned error messages in dmesg output

I'm using the current stable kubuntu version (jaunty).
$ uname -a
Linux sunshine 2.6.28-13-generic #45-Ubuntu SMP Tue Jun 30 19:49:51 UTC 2009 i686 GNU/Linux

As the drive can't be ejected even after killing the growisofs process, I guess, that this is not entirely an growisofs bug.

BR,

Holger
