There is one test for the ISO that is never wrong, it will confirm a good or bad download: the md5 checksum. If it is right you don't need to do another download and will gain nothing in doing so.

There is a chance that a bad burn or bad media resulted in a bad disc that the md5 checksum would not catch. Testcd might or might not catch this. But it's not the right tool for deciding if you had a bad download.
