No.  Cable/Satellite boxes transmit the already-decoded signal over
component (analog HD) or HDMI/DVI (digital HD) to the TV.

Firewire to mythtv works great (I use it with my comcast digital cable
setup).  You might be able to get a satellite box with firewire from
169time.com, but it's expensive (I'm assuming that it's legal since
they're still in business).  composite and svideo are not HD, and an
HDMI-enabled encoder would take WAY more processor power than you can
afford (there are a couple of HD encoder cards out there that range in
the 4-5 figure price range)

commandline script that mythtv calls.  I used exactly that setup (dish
-> svideo -> pvr-150) for a couple of years before switching to comcast
and firewire.  google "losdos mythtv" for some info.
