Ah, it's a Pentium 4, 2.4GHz (I think, might be a 2.8GHz)

I was watching BBC HD (think thats 1080i), both pre-recorded and live 
streamed from my existing backend over gigabit LAN and it was using 
20-30% CPU.

Previously when this box was a combined BE/FE without VDPAU it didn't 
have enough get up and go to play BBC HD without stopping every 3 
seconds or so.

Very impressive!  Many thanks to the developers who have worked on 
VDAPU.  At the minute I've only patched my secondary frontend - I'm 
waiting for the official 0.22 release before I upgrade my main box.
