Of course it does. It wouldn't be Ubuntu if it worked on more than one version

The straightforward way to get what you need on 12.10 would be to install a plain-vanilla Xubuntu. Set the machine up with one user account --your main user. Set it up on static ip. Rip out some of the more obvious things that will be useless for a dedicated PVR, if you wish, like games, graphical e-mail clients, most/all office apps/applets, etc. Install the "mythtv" meta-package and allow it to install to its defaults. It will create the mythtv user and ancillary claptrap. If you use a storage drive for myth recordings, make a mount point for it under the automatically created /var/lib/mythtv/ , mount your drive there, make sure the ownership all the way down to this storage drive and its files is mythtv:mythtv, permissions about 775. Put the mount point properly in fstab. And run the backend setup. When you can watch tv through the standard mythfrontend, like a standard Mythtv machine, then add XBMC, using your script.
Your way with the mini.iso distro should also have worked, and will end up significantly leaner. Clearly your step 5) is where things got off the track. Also, you shouldn't strictly need mythbuntu-desktop (or even XFCE, which certainly is not low-resource any more), just X and a lightweight WM, particularly on a display where XBMC will eventually be the star, not Mythfrontend. If you like editing xinit.rc files (and who doesn't) you might prefer IceWM (which I use a lot on frontends) or possibly even fwvm or fluxbox. And your backend is intended to be a master backend (it will own the database; other machines will connect to it), so "mythbuntu-backend-slave" was also presumably unnecessary.
Finally, the reason I asked whether in your current installation your backend was really running in a usable fashion as you believed (i.e. it could receive TV) when started from the CLI as your regular user without sudo, is that if I were confronted with that circumstance where the backend actually was functional for tuning/watching/recording when run as the normal user, then I would be strongly tempted to simply add
to my startup apps in the XFCE (or derivative) desktop and call it a night. The way these things usually sort themselves out, after the machine has been running along for a few weeks, inspiration as to how to correct nagging little issues will strike with a slap to the forehead and untangling something like this will end up as an hour project some weekend.
