from the man page I quoted earlier:

       If  the  media  already carries isofs and growisofs is invoked with -Z
       option non-interactively,  e.g.  through  cron,  it  shall  fail  with
       "FATAL:  /dev/dvd  already  carries  isofs!" Note that only ISO9660 is
       recognized, you can perfectly zap e.g. an UDF filesystem  non-interac-
       tively.

This explains why it works directly from the shell, and fails in the
script.  growisofs senses it's being run from a script and changes
from WARNING to FATAL.   (I'm guessing there's a bug and it prints
WARNING in the error message, but aborts anyway.)
