[mythtv-users] HD on CN700 MSI MS-7199 board?

[Thomas Kessler]

I'm still trying to get this to work. Even though I read on the openchrome
site that the cn700 can only do 1024x1024. I figured I would try with
mplayer first and mythtv second. Mplayer is built from source with xvmc vld
support. Mplayer is running with these options: mplayer -vo xvmc,xv -vc
ffmepg12mc, ai.mpg

Here's the output:

Does anyone know a way to get HD material to run on the cn700? Can someone
tell me what is going on with xvmc above? I know this is a mythtv forum, but
a bunch of people here know a lot about mplayer and I don't feel like
joining  another mailing list.
