When you state that you are 'not able to successfuly sum -check (I
assume you mean md5sum here) CDs', are you referring to the md5sum of
the ISO file, or the CD itself? Do the ISO file(s) match the listed
md5sums for the download?

Note that the md5sum of the burned CD will not match those of the ISO.

So, the ISO md5sums do match. That only indicates that the ISO file is
good. The issue seems to be that the burn is not correct as when you run
the 'Check CD' it verifies the files on the CD against the md5sum.txt
file on the CD. When you:

you can check the error files md5sum against that md5sum.txt to see if
they are actually bad on the CD, or if a R/W I/O error is causing the
problem.
