Xvideo is one of the X11 server extensions. Its used for accelerated 
video rendering. The extension presents as one or more "adapters". In 
the case of many of the Intel video chips, there are two one of which is 
the overlay video adapter, the other the textured video adapter. The 
latter tends to be more cpu intensive but is more up to date.

The XV API lets the application list the adapters and their capabilities 
and choose which to use..

If you run "xvinfo", you can see the choices.

Mplayer and vlc both have options to let you select which adapter. As 
far as I know mythfrontend just uses the first in the list, and I was 
asking if this is still true.

The alternative is to set an option in the xorg.conf file to set the 
order that the Xserver will give the adapters in the list. However, this 
means restarting the server to make a change.
