Now, when I use the 4.02 CD version, it boots up fine. I only have this issue with the DVD.

Any ideas????????
Have you tried any of the cheatcodes? Specifically: (at boot) knoppix xmodule=ati
If you have tried that then I would shell-out (do Alt+Ctrl+F2) then cd to /etc/X11/XFree86-Config and see what is listed for the video driver.
