I'd like to put some extra big files on the knoppix boot disk, some vmware images

That stuff will not fit into the 700M of a CD. I created an image (which ended up being about 1G) using the regular remastering instructions. When I tried to boot, I get an error during boot:

Accessing KNOPPIX CDROM at /dev/scd0.../modules/cloop.o: init_module:
Hint: insmod errors can be caused by incorrect modules parameters, including invalid IO or IRQ parameters
Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.

...

Does anyone know how to make KNOPPIX work off of a DVD? It'd allow me to put tons more stuff on that disk. Whoot.
