Very good approach. My goal is somewhat different, though.

Well I will use the PC/CPU not only for Myth, but two users will also 
access it remotely via X Window and run Mozilla, Gimp, Kmail, OpenOffice.

 From what I gathered so far in this discussion, I suppose that:

with Pinnacle PCTV Pro (no mpeg), and when watching live TV with instant 
replay - commercial skipping active, about 1,5 GHz of CPU might be consumed.

OTOH with Hauppauge PVR-250 in the same situation, the CPU impact would 
be negligible (considering an Athlon 2500-3000 MHz class system).

Am I right?
