I got no such trouble.
The differences in my and your usage of growisofs seem to be :

- I use option  -use-the-force-luke

- I run  mkisofs  and  growisofs  separately in a pipe :

    mkisofs ... | \
    growisofs -use-the-force-luke -dvd-compat \
              -Z /dev/sr0=/proc/self/fd/0


About cron : the shell environments used by cron often lack
important variables. If you find no other reason for growisofs'
refusal, maybe you put it into a script and prepend the full
output of command env executed in a dialog shell.


Have a nice day :)
