This is mostly a reminder for myself... but it might help you out too.
growisofs is used to burn the dvd onto the device.
/dev/dvd is a atapi device (no scsi emulation).
/mnt/dvd is the dvd you want to burn, it this example a mounted DVD image was used (mount -o loop /tmp/dvd.img -t udf /mnt/dvd)
growisofs -Z /dev/dvd -V "Volume Label" -dvd-video /mnt/dvd;eject
