Suggestion: Don't do an MD5SUM check. Instead, read the whole CD with:
dd if=/dev/scd8 of=cpybak
and then use 
cmp cpybak original.iso
to check byte by byte the copy against the original

But DO do an MD5SUM check of the original.iso on your disk with the source
from which you downloaded, of course.
