If you're using the atrpms version, then xvmc support of the Via Unichromes
isn't included, as it's specific to one piece of hardware (atrpsm used to
have a mythtv-via set, or something like that. Some discussion of it's
demise is somewhere on the atrpms site, but I can't remember where).

As far as I know to enable xVmc you'll need to download the source and
compile your own. Source tarballs are linked on the www.mythtv.org homepage
- you don't need to go the whole hog into SVN unless you want the bleeding
edge. Don't worry - it's not actually all as scary as it seems, even if
you're not used to compiling from source one just follows the
instructions...

There's a series of compile options that enable the xVmc functions, and then
a configuration item to use them will appear in the setup menus. More
details in the wiki on http://www.mythtv.org/wiki/index.php/XvMC

A nice quick way to check the use of xvmc on via is to look at the onscreen
display when playing any recording - with xvmc this will be limited to grey,
but without you'll see it in colour...

Hope the helps.
