I hope that you intended to say "Anyways, in one of my DVD drives, it doesn't work at all,...".

The "failed to insert cloop or something rather" message sounds to me like a bad burn (we frequently see this type of thing when the disc has been burnt at a high speed). I'm not certain of that because I would not have expected the system to get far enough to get into the scrambled video mode if it had the failed to insert cloop or something rather error, but such errors can be pretty flakey, you might get it some times and get other errors on other boot attempts. My suggestion would be to use the Get Knoppix link near the top of this page and download a new ISO with a BitTorrent client, read the downloading faq all the way through, and burn a new copy at a slow speed. You might want to start with the CD ISO rather than the DVD ISO, that way your have a more universally useful Knoppix CD and if it turns out that your DVD is OK you'll have both (you can always get the DVD later if you do need a better burnt copy). You very likely may still need the cheat code to get your monitor to work right, but you should not see the failed to insert cloop or something rather error on a good burn.
