I'm an Nvidia user myself, but I'm pretty sure that without 2D 
acceleration you won't be able to get acceptable performance.

In the Nvidia world, we're in a similar situation with the open-source 
'nv' driver that most distros provide - it's pretty much not recommended 
to use this driver as the performance for displaying video just isn't 
there, and we need to use Nvidia's proprietary driver.

Does your card/driver combo support OpenGL?  MythTv 0.21 has added 
support for OpenGL rendering that works well, from what I have heard.

Otherwise I know there are people who use the propietary ATI driver with 
great success - search the wiki if you're interested.
