Yes - but don't count on the performance being that great. VIA claim
it's good enough to run compiz. Not that you'd want to on a front end.

I'm using Ubuntu 7.10 1and the mythtv 0.2.20 packages from the Ubuntu
repositories. SVN should work too, but I wanted to work with something
more stable!
I used the alternate install disc, and installed a command line
system. Then I installed ubuntu-mythtv-frontend, which installs X too.
I downloaded the VIA driver installation package from
http://www.viaarena.com/default.aspx?PageID=420&OSID=45&CatID=3220&SubCatID=184
This provides a script you can run which installs the driver and
updates xorg.conf.
Then I set up the build environment to build mythtv:
sudo apt-get install build-essential
sudo apt-get build-dep mythtv
Then I got the mythtv source:
apt-get source mythtv
I only needed to change two files in the end.
1) In libs/mythtv/vsync.cpp, comment out the following line in
VideoSyn::BestMethod (line 95):
//TESTVIDEOSYNC(DRMVideoSync);
2) In libs/mythtv/VideoOutXV.cpp, uncomment line 67:
#define USE_ATI_PROPRIETARY_DRIVER_XVIDEO_HACK
Then do the configure/make/make install thing, at it should all work.
That's all from memory, so I might have forgotten something. If you
get any problems, let me know.
