I think I see your first problem, from the growisofs manpage:

       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.

So it changes behavior depending if it's called directly or through a
script.  (bad design!)

And my best guess is your disc isn't getting blanked for some reason.
I don't really have experience to know why that would be.

try dvd+rw-format -force=full ?

Also, from the FAQ:
http://www.physics.ucsb.edu/~pcs/apps/linux_dvdr_burning.html

   Occasionally, running multiple burn sessions sequentially in a
single login (even if you eject and re-insert the DVD) makes  the DVD
drive inaccessible.  This seems to happen more often when an
automounter (autofs or the Gnome or KDE automounters) of any type is
running and notices the DVD.  The only known fix for this is a reboot.

Mark
