I guess my biggest concern with Cablecard is the same as my concern
with QAM and Firewire - you are at the mercy of the cable company.  In
theory they can work great, but at any time some of your channels
could stop working, and your only recourse is the legendary cable
customer service number.

I've always tended to rely on using a tuner box and controlling that
box.  It is definitely a lot more kludgy, but it doesn't rely on
magical "do-not-copy" flags/etc.  Depending on your tuner you could
end up getting on-screen displays in your capture - usually there are
ways to minimize that.

Now, historically that would only work with standard def.  However, my
understanding is that you can now get hardware capable of realtime
mpeg-4 compression of HD from DVI/HDMI (perhaps going through a device
to remove HDCP first).  You will lose a little with the transcode, but
it will be HD, and you're immune to upstream provider tampering.

However, when it works clearly cablecard or QAM are simpler and
generally better solutions.
