Victory! I had to use the partition tool on the live DVD. I think the problem is that it didn't want to change an EXT3 partition to an EXT4 partition. So I had to manually delete the old partition so the installer could do it's work. I'm assuming this is a bug in the latest installer..... Anyway so far so good. Video and audio are set up and working. Haven't tried coaxial digital audio output yet, but that's on my list. So far so good.
