This is an important point. I'd like to guess how much GHz CPU cycles 
(very approximately) difference is there.

Could you please compare

- a PVR-250 with AMD Athlon 3GHz,

- a Pinnacle PCTV Pro  with AMD Athlon 3GHz?

When I want to record a broadcasting, and do commercial skipping, how 
much CPU cycles (GHz, rough estimate) would be left for other unrelated 
tasks on the PC ?
