k3b (KDE's CD burning program) has the annoying habit of converting the file names to upper case (in addition to mangling them). I am sure there is an option somewhere to prevent this, but being too lazy to locate this option, I installed the Gnome version (nautilus-cd-burner). No such problems; works like a charm. In addition, nautilus has the option of zooming in and out using the scroll wheel when viewing images (comes in really handy for porn ;-) )
