If the md5 of your CD doesn't match with the corresponding md5 from the website, it means your .iso file is corrupt so you'll have to download it again.
Make sure to compare the good md5 since each .iso, thus each edition will have a different one.
To avoid wasting CD's, check it after download and one more time after burning your CD.
Make sure that you burn your CD at slow speed and that you select 'burn the disc from an image' or any similar option.
