You cannot use growiso with the acd driver, you need the cd
driver which is provided by atapicam facility.

You can simply load it via the kldload command if you don't 
want to rebuild your kernel.

Oh, it seems that you already have the atapicam / cd setting in
your kernel running. Fine! Just change the command:

	# growisofs -dvd-compat -Z /dev/cd0 -J -R disk1

This should work.

I have a symlink set via /etc/devfs.conf as /dev/dvd@ -> cd0
so I can use the command

	% growisofs -dvd-compat -Z /dev/dvd=foo.iso

as presented in growisofs's manpage. :-)
