</div></div>right, but not all GPU acceleration is made the same, the older cards<br>
were not capable of the support required for typical MythTV file<br>
playback, especially with deinterlacing taken into account.<br>
<br>
It's not the CPU speed I'm concerned with but the GPU<br>
speed/capabilities. If I go and buy a Sandy cpu with "INTEL HD", and<br>
connect it to my 1080p tv can I expect the quality of it's 1080i<br>
playback with deinterlacing to be on par with what I get from my<br>
NVidia GT220 in regards to CPU load reduction?</blockquote><div><br></div><div style>Ahh... now that is a completely different question than "<span style="font-family:arial,sans-serif;font-size:13px">is there a list of processors that work with VAAPI and "should" be</span></div>
