I'm trying to boot knoppix off the cd but it gets to the stage where it says

Accessing KNOPPIX CD at /dev/hdc... /cdrom/KNOPPIX/modules/insmod: 1: Syntax error: redirection unexpected
Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.

I've verified my CD with md5 and it's okay. I also burned at 4x. I've also tried buring on different media. I've tried the command knoppix nodma. I've tried expert mode. None of these methods work. I'm pretty concerned about the syntax error thing.

Can somebody please help?
