So maybe someone did use mkisofs and -hide-joliet...

So the size is OK (nearly 300 MB).
YOu could try to run star -c -onull on the
mounted FS in order to check whether the du command gives you
the correct info.
You also may use "isodebug" to find the command line used to create the image
in case the image has been created with a binary compiled from the
official mkisofs source.
