I just got my HDHomerun and if I send the stream to my Windows P4
2.4GHz desktop machine it renders the direct HD stream without any problems (I didn't check the CPU utilization under Windows). I don't understand why there is so much fuss about HD decoding under Linux (but I'm pretty ignorant :-).

</blockquote><div><br>Well, my situation is different. I still get 99% CPU utilization without XvMC. At least with XvMC it seems like the video is running at (or close to) real time whereas without it the video looks like slo-mo.
<br></div><br>I'm totally bummed that my Myth system can't seem to handle HD. I'm still sorting through all the different advice on the mailing list but it is still surprising to me that this machine strains so much under the HD load whereas my Windows machine (which I did *nothing* to optimize) handles it so easily.
