Wim,<br><br>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.

drivers from VIA contain support for most chipsets, mpeg2 and mpeg4
acceleration, but are of low quality and often unstable. In addition, the 3D
driver leaves your system open for attack by malicious clients, and furthermore,
applications that accelerate mpeg2 and mpeg4 must be run as root, which is a <b><span style="font-weight: bold;">very</span></b> bad idea if they contain
vulnerabilities (and they do). Avoid using these drivers unless you know what
you are really doing! The drivers can be found </span></font><font color="black" face="Verdana" size="2"><span style="font-size: 10pt; font-family: Verdana; color: black;"><a href="http://www.viaarena.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

Wim,<br>
<br>
I think the biggest question you'd have to look at is does Myth support the
features that the driver seems to support in the chipset. The Unichrome drivers
have been developed to take advantage of the MPEG-2 hardware decryption (via
XvMC) and then these drivers are leveraged in MythTV. I'm not sure the same
would be true of the via drivers.<br>
<br>
I have an SP13000 with a CN400 chipset and I also have the DVI-02 daughter
card, so I'm quite interested in what else you can find out about this new
motherboard and whether the drivers implement some standard Linux and/or Xorg
video acceleration specification.<br>
