That does seem silly, because of this line on the k3b website:
"The actual burning in K3b is done by the command line utilities
cdrecord, cdrdao, and growisofs."
I'd give it a try anyway, but I need something gui-less.. And it would
appear I'm already using the command-line utilities that form the back
end of k3b. Though perhaps it's an issue of fancy command-line options
that k3b uses..
