so i downloaded knoppix 5.1, verified the md5, and burned the iso to a cd (used nero trial so i could have it verify the burn afterwards). i reboot the computer, get the "welcome to knoppix" message, then after that it says it can't find knoppix file system.

i've been scouring the internet to find answers, but can't find any that i have not yet tried.

i've tried burning at a lower speed. apparently 4x is both as fast and as slow as my drive can go.
i've tried knoppix nodma at the boot screen.
i've tried burning to several different cds.
i've tried several different burning programs.

so unless anyone has any other ideas, i'm stumped.
