You may be victim of several bugs. The DVDs are probably OK. The media
test is not working. Also, if you log into the gui without first
logging into a text terminal (CTRL-ALT-F1 for example) as root and running
yum update gdm
you will not get a useable screen. You must also manually add a normal
user as root - the firstboot program is also hosed.
