[mythtv-users] VIA EPIA EX-series Mini-ITX Mainboard

[Kevin Slater]

Wim,

I do believe that most everyone who are using MythTV with via EPIA
motherboards are using either the Unichrome or the Openchrome drivers as
that's what's documented in the setup guides, etc. I used the via drivers a
couple of years back and you did have to run as root to be able to take
advantage of the accelerated features. Perhaps that's changed, but the only
way to know for sure would be to switch to their drivers again. Since that
involves a fair amount of setup, and considering that my 2 frontend/backend
EPIA systems are constantly in use and work pretty well the existing
drivers, I won't be able to help with this discovery process. I am
interested though.
