Have you sometimes wanted to copy a cd image to your hard disk while you are using linux/unix. Here is a simple way that requires no additional packages, but no GUI,
dd if=/dev/cdrom of=/tmp/cdimage.iso
If you insist on a GUI, you could give a try to GnomeBaker as well. If you are using yum on fedora core 6 use yum to
yum install gnomebaker
GnomeBaker can burn cds as well, but there a few minor bugs; no harm will be done to your burner or disk. I
managed to successfully burn a Ubuntu Live CD and boot from it, that is enough assuarance for the moment.
