[mythtv-users] Dual HDTV Tuner Requirements

[Jonathan M. Cooper]

Thanks for your response.  Does that mean that PIP is not feasible with,
say, a P4 3.2GHz?

Note that this is only an issue at playback time. Recording is more or
less a 
simple matter of writing the incoming mpeg2 stream to disk, very little
cpu 
usage.

2 HDTV tuner cards and a FireWire cable box here (and a few more analog 
tuners).

Not much difference from a system handling one HDTV tuner, though you
may want 
extra cpu headroom if all commercial cutting runs on the same box you're

viewing with. With recent HDTV playback performance improvements, I
believe a 
3GHz P4 w/512MB of RAM and a GeForce FX 5200 or a 6200 should be
sufficient 
for what you're after.
