I've missed the majority of this thread, but have you tried installing nvidia-current-updates (this updates the nvidia driver to one that wasn't necessarily in the first release). There's also an nvidia-experimental driver which is even newer (don't let 'experimental' put you off, all of Linux is experimental :) ).

Failing that there's an ubuntu-x-swat/x-updates PPA that regularly pulls in updated drivers and versions of X.

You may got some mileage from this.

There isn't a mythbuntu 12.10 - they're only supporting LTS releases from now on.
