</div>If you're only running 15% CPU running the software decoders, why even<br>
bother with hardware decoding? In any case, you should be running the<br>
OpenGL renderer rather than XVideo if at all possible.<br>

I have not experimented with VAAPI as yet. However, I do have an i5<br>
2405S running Myth 0.24 quite successfully. My experience is described<br>
in this thread:<br>

I had an initial problem with mythfrontend crashing whenever I attempted<br>
to use OpenGL. The crash was as you experienced. We identified the<br>
cause as a null pointer reference in the mesa 3D driver, reported the<br>
problem to <a href="http://freedesktop.org/" target="_blank">freedesktop.org</a>, and patched mesa with their proposed fix.<br>
Since that time, we have had no crashes and video quality is excellent<br>
using OpenGL. The fix to this bug was committed to the mesa repository<br>
last week and can be seen at:<br>

The patch is quite simple and involves one function in<br>
mesa/drivers/dri/intel/intel_<div id=":2r">screen.c. Another person on this list<br>
reported that the patch solved an identical crash for him. Before<br>
diving into much debugging, I suggest you apply this patch to the mesa<br>
7.11.2 code, recompile it, and give it a test.</div><br>
