I was talking to Keith Packard last week at OSCON about the joy of  
trying to decode 1080i H.264 frames on Linux compared with Windows.  
Basically for the next 6-12 months we need a damn fast CPU.

Can anyone estimate the grunt required for full 1080i playback in AMD  
and Intel CPU form?

For a combined frontend/backend solution I'm personally considering a  
Tri or Quad cpu setup so that we have N-1 CPUs for the graphics decode  
and a spare CPU for any backend housekeeping tasks.

Next part is the capture device. My ideal would be the HVR2200 for DVB- 
T but that isn't ready yet. Also the HVR 3000/4000 units aren't  
mainstream either.

We definitely live in "interesting times".
