So you want to take the two video outputs, run them through (expensive)
modulators to have two channels on a single coax, split that coax between
the two inputs, demodulate the signal, and pass that through the encoder
chip? Why not just run s-video directly into the baseband inputs of that
card? Seems like you're making things needlessly complex and expensive.

For HD capture, the only option supported is the Hauppauge HDPVR.

Chances are there is no consumer RF transmitter you can purchase that
would
be able to communicate with the box. Your most likely bet is to tear open
one of the remotes, and wire up an interface to simulate button presses
through a serial port. You might want to ask on AVSForum. Some brief
searching
turns up several threads on the topic, but I haven't found one with an
actual solution.
