I'm not certain why, but I've had a hell of a time with installation on my core, and I blame it on me using the DVI connection for a monitor.
I know this sounds silly, but the AV wizard doesn't seem to like the DVI connection. I switched to a vga cable connection, and it worked right out of the box.
Can anyone explain why this is?
If I missed something in the wiki relating to this, I apologize in advance!
