Jim, you need:

-a video card that supports XvMC (NVIDIA)
-an NVIDIA driver that doesn't have broken XvMC support (generally
7676 is advised)
-myth compiled with --enable-xvmc
-the XvMC codec selected in the mythfrontend setup

Possibly other stuff I'm forgetting, but someone will probably chime in if so.
