Guessing that you upgraded from FC2?  Anyway it looks like the gnome
cdwriter thinks you are using a 2.4 kernel which requires SCSI
emulation.  Two work-arounds are to use cdrecord from the command line
(use man cdrecord to see options) or use the k3b program that comes with
FC3.  I highly recommend k3b as one of the most polished programs.

the cdwriter is configured in /etc/cdrecord.conf  if you want to try to
reconfigure that.  You might even find a cdrecord.conf.new that probably
would replace the other, though I don't know for sure.
