problems trying option to upgrade fedore 6 to fedore 8
I've downloaded the fedora 8 dvd iso from 3 different sources, each time after I burned and boot with them, and try the upgrade option, they give an error on the media check. If I continue anyway (not recommended, but did anyway) it eventually freezes during package checking (over 1 hour of no activity).
Is there a bad version of the iso that's been distributed? Does the upgrade option not work? Something specific to my machine (no other problems that I am aware of).
