At first I only went to the first option and of course didn't really get anywhere easily from there. if you go straight to install linuxmce you should be fine. As soon as the kubuntu install is finished, you should start the installerscript for linuxmce. The only obstacle is the nvidia driver really- you should use basic ui for the first generation of the orbiter- once everything is finished, got to kde-desktop, open a terminal and run nvidia-xconfig. Reboot from there and go through the AVWizard again, this time you can select ui2 with alphablending- it should be using nvidia 195.22 then.
