[TriLUG] OT: dual-layer blank failure rate

[Brian Henning]

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..
