This is the last xorg.conf which I bothered to save prior to moving to 
an HD capable screen, and an HD capable motherboard, so this is standard 
def output to a TV using S-Video. The Via boards require setting, in the 
BIOS for output to a CRT and/or through the TV output (S-video), as well 
as in xorg.conf. The openchrome driver is the default driver for Via 
boards in Fedora and should be available in other distros. It handles 
xvmc quite well. It can actually do HD mpeg decode but only to a 
1024x1024 sized frame with the correct chipset (CLE266 etc). ISTR that 
the M10000 is a little below the SP13000 which I had, but it should do 
standard def tv without straining itself. XvMC configuration is picky 
but well described in the docs at openchrome.org and on the mythtv wiki.
There are some settings caveats but it is doable.
