Selecting a Video Output Driver

I posted a message about this awhile back but haven't gotten a response,
so I'll try one more time just in case anyone missed it.

Is there a way to select a video output driver (like in mplayer) such as
"directfb" or "gl" or "gl32" ?? The reason I'm wanting to do this is
because for some strange reason, anything that uses XV while in
fullscreen mode looks like crap. I have yet to figure this out, but
meanwhile I'd like to see if I can use other drivers. I've tested the
output from /dev/video using mplayer and those drivers and it looks
better, so if there was a way to change it in MythTV that would be great.

You could run mythfrontend with the environment variable "NO_XV" set. This
will cause it to fall back to using MIT-Shm, which is slower. There is
currently no support (AFAIK) for direct framebuffer, SDL, OpenGL or any
other output.

You'd have to write another video output driver for that to happen.

yeah, unfortunately, the NO_XV option is pretty slow and unusable... I
guess I'll just have to try and figure out my XV problem, although I
wonder if I'll ever figure it out -- I have no clue what is even causing
the problem. As soon as I get a digital camera I'll take a picture of
my monitor (an old-fashioned "screen-shot") so I can show everyone
exactly what I'm talking about.
