Your setup of mythvideo may be different but I've got mine setup to run
mplayer using the xv video output (it was the default). Mythvideo just
calls mplayer with the command line you configure in Utilities/Setup ->
Setup -> Media Settings -> Videos settings -> Player Settings.
You can compile mplayer with xvmc support (i.e. run configure with
--enable-xvmc) and then make your mythvideo command something like:
mplayer -fs -zoom -quiet -vo xvmc %s
Mythvideo is working great for me so I'm going to leave mine using xv.. unless
anyone has a compelling reason to use xvmc?
