I almost forgot that you are using SuSE.
The SuSE CDs have an Integrity check built in them.
So, the CDs check themselves and give the results.
It would be better if you download the ISO again.
What about the Other ISOs?
Check all of them....and redownload which are corrupted (whose MD5 check doesn't match).
Take care while downloading further Images......you have learnt it the hard way it seems!
MD5 sum checks are very very very important.
Do tell all your frnz too.....if you find them downloading Images.
