I am cluess to why this happens. But at least I have found a workaround, that allows me to boot to knoppix without any DVD: Win Partiton.
Basically it comes down to letting windows bootloader boot the grub bootloader. Grub will then accesses the knoppix iso image on your NTFS file system and start it. It already works on my laptop, and soon i will install this on my P4 rig, too.

P.S.: When the error mentioned above happends, my system continues booting from DVD, no hanging here on my system. So i am afraid, you should start your own thread, giving it a meaningfull title, describe how you try to boot knoppix (parameters, media, version), what your system looks like etc.
It looks like our problems are not related. First thing to do is a testcd to finde out if the cdrom is ok. Have a look at the cheatcodes for the boot parameter.
