K3b cannot find growisofs

[maxrussell]

I've followed the guide on k3b as a non-privileged user, although K3b still complains that it can't find an optical device.

I've got devfs.conf looking like this:

own     acd0    root:users
perm    acd0    0660
link	acd0    dvdburner

own     cd0     root:users
perm    cd0     0660


own     acd1    root:users
perm    acd1    0660

own     cd1     root:users
perm    cd1     0660

own     pass1   root:users
perm    pass1   0660

own     pass0   root:users
perm    pass0   0666
perm	xpt0	0666

However, when I run it as sudo, it can't find growisofs. It is installed in /usr/local/bin and I've upped it to first in the searched paths in k3b's config.

I'd like to burn backup DVDs. What should I do?
