In my experience that happens because one or the other of the
images has "extra" garbage blocks past the end of the actual
ISO filesystem image.  If you look at the ISO filesystem header
and find the actual size of the image, it's probably smaller
than the "image file".  If you only compare the bytes within
the ISO image itself, I bet the two will match.
