The obstacle is that there are no consumer-grade cards that can
capture from an HDMI port. You're looking at a pro card for many
thousands of dollars if you want to do it. The HD signal is
downsampled when output on S-Video so you will be only getting a
standard def signal. Of course, it will be a REALLY nice SD signal,
but SD none-the-less.

Cable is definitely easier with the right box. Firewire from the STB
to Myth and you're done with the hardware part. However, you will run
into limitations with encrypted channels that you don't have to worry
about with satellite. Unfortunately, there is no single good solution
that works for everyone. My cable system sucks, so I went with
satellite and only OTA HD. If they had a better line-up and weren't
evil, I would switch to get HD content via a cable STB.
