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<br>
<br>Here's the output:<br><br>MPlayer 1.0rc1-4.1.3 (C) 2000-2006 MPlayer Team<br>CPU: VIA Esther processor 1000MHz (Family: 6, Model: 10, Stepping: 9)<br>CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1<br>

Hi all,<br><br>I'm having no luck pushing HD material on my MSI MS-7199 board. It's a Via CN700 Unichrome Pro video chip set. I've tried the following:<br>- compiled openchrome drivers from source<br>- set xorg.conf driver as openchrome<br>
- built mythtv-0.20 with: --enable-xvmc-pro<br>- went through xvmc page on mythtv wiki for help<br>- even tried building mythtv w/<span>xvmc_buf_attr->SetNumSurf(1<del>2</del>) and </span><span>max_num_xvmc_surfaces(1<del>2</del>) (as discussed here: <a href="http://svn.mythtv.org/trac/attachment/ticket/3035/mythtv.diff" target="_blank">http://svn.mythtv.org/trac/attachment/ticket/3035/mythtv.diff</a>)<br>
<br>Normal TV works fine. HD is choppy and there a bunch of prebuffering messages.<br><br></span><span>Anyone got some ideas. </span><br><font color="#888888"><span><br>TK<br></span>
