 Can you be sure that mplayer is using vdpau and is not using software
 decode or failing over to software decode as we are? You can look at top
 and see the cpu usage to find if it is using software decode. If you
 compare that to cpu usage of MythTV using vdpau hardware decode (h264
 video that plays in MythTV using vdpau without failing over to software),
 you can verify if mplayer is really using hardware decode.
