I was unable to install Fedora 9 from a DVD. Unable to get a Video during Anaconda install. May be my Video Card or something (GeForce 6600 GT). Frustrating as it hung with no useful interface at a very early stage in the install.
I had no real issues installing F8 on a complete install. Must be something changed in the installer, or whatever, as my machine has not had anything changed on it. Hopefully these issues will be resolved before final release of F9.
