For those that are curious, the size of the KNOPPIX file is different if you sort it, like I suggested. However the difference is miniscule.

Another good tip, you can run "isoinfo -d -i /dev/cloop" after you have inserted your cloop module on the cloop image of your choice. This allows you to look at ISO info that is otherwise not visible.

Granted I still haven't solved my problem.
