brasero,dvdrw and libburn

[gula nito]

Hi.

I need to activate the libburn backend in brasero cause I need support for
DVD-RW.
(I have support for CD,CDRW and DVD, but a DVD-RW is not recognized by
brasero. I read http://forums.freebsd.org/archive/index.php/t-3586.html and
the cause of that problem seems to be that whit the default backend there
aren't DVDRW support).
I was compiled brasero from ports yesterday  whit the libburnia option
activated, but in the gconf-editor I can't see the lbburn_iso nor the
libburn_burn keys for activate it.

Thanks in advance.
