I have a P4 3.0 GHz as a frontend only, and while it can display 720p/1080i<br>
just fine (did not test 1080p), any deinterlacing of the 1080i content<br>
pushes it over the edge and playback gets jumpy.<br>
<br>
Another frontend with a 3.2 GHz Pentium 4 does deinterlacing with kernel and<br>
linear blend, but not with yadif or greedyh.<br>
<br>
Then I have a backend AMD BE-2300 CPU. Just for testing I installed the<br>
frontend and connected a monitor. It plays smoothly even with yadif and<br>
also with greedyh, but can't handle yadif2x or greedyh2x.<br>
<br>
The testing was all done with source material broadcast in the US, meaning<br>
all HD is actually in MPEG2, not H264.<br>
