Ah  HAH. I just noticed something.
You have (like I have) the SP13000. This uses the unichrome-pro chipset.

Accordingly, you should configure mythtv with all of  extra  
configuration switches enabled.

use:   --enable-xv --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro    
(especially the last!).

Run ./configure --help or open it with vim to see all of the defaults 
and switches.

NEXT.  make sure that you have a file   /etc/X11/XvMCConfig which has 
one line in it:   libViaXvMC.so.x.x (or possibly its libXcMCVia.so.x.x: 
the Nvidia one is libXvMCNVIDIA_dynamic.so.1 but ISTR that the Via one 
does not include the 'dynamic' bit.).

Man this stuff is obscure!. Some of it is mentioned almost in passing on 
the openchrome site.
