I'm starting to understand, the periods really help.

I've burnt a CD with a live CD. This was some time ago. I have not used k3b but see no reason that it should not work, but I do recall some mention that there have been some burning issues (bugs) in recent releases. You might want to look at the bug report section in the wiki or search the forums for any known issues. Of course, if the Live CD is still in the CD drive and you only have one CD drive, then these is going to ba a conflict; you can't remove the Live CD and still be running Knoppix from CD. I solved this in two different ways: First I used DSL, which only takes 50 meg, and then wrote to the same CD that I had burnt DSL to on a second session with the burning software included in DSL. Second I realized that I could just use the toram switch to load DSL to memory (I didn't have enough memory to load all of Knoppix to memory), which let me swap out the CD and put in a nice fresh blank one. And on systems with multiple optical drives Knoppix can stay in one while you burn to another.
