The "mediacheck" in the installer checks for the embedded md5-sum in
the application-data field in the ISO-header. Anaconda used to contain
the utilities that are now separately available in the isomd5sum
package. You should be able to use this to check the md5sum of the
downloaded .iso, before you burn it.
