Actually, nautilus-cd-burner's README.Debian states:

 "This code detects available CD writers by examining files in /proc.
  It will try /proc/sys/dev/cdrom/info which is created by the 'cdrom'
  module, and /proc/scsi/sg/devices which is created by the 'sg'
  module.  One of these modules must be loaded for nautilus-cd-burner
  to work."

So, check if the appropriate modules are loaded, then have a look on the
kernel side (which Kernel do you use? can you test 2.6.26 or 2.6.30)
