The question that you ask is very vague, because you
don't mention what capture hardware you have. An
analog BT8x8 card is much more CPU intensive than a
PVR-x50, for instance.
I don't think that you can capture an HD stream
(though I may be wrong on this). There are no HD
capture cards that I'm aware of (the bandwidth for HD
is insanely huge), and the set-top boxes that support
Firewire output downsample the output (how far, I
don't know).
You can capture ATSC HD with an HD-3000 or an Air2PC card as well as
firewire. Both are supported. I believe there are DVB cards for
non-US HD capture as well.
Any DVB card can capture HD, provided HD is available. This is
irrespective of whether it is MPEG-2 HD or H.264.

P.S. I'm curious when DVB-S2 cards will appear on the market.
