OK, thank you.

I have the cables I need already, though I have deiced I would want to
build a dedicated box for MythTV.

I never thought about the sounds from the cable box (I'm glad I asked
questions :), but could I not use the coax out from the top set into
the MythTV box and then composite from the MythTV box to the TV?

Let me get this straight, the IR Blaster is part of the capture card
that will change the channel on my top set? Also, you mentioned that
there will be some delay when changing channel, how long of a delay
should I be expecting?

No I think I understand it all now, with the exception of the
questions above... Also, I read the required specs somewhere and I
can't seem to find them any more, I'm sure I'm over looking them...
But a PIII ~500Mhz, too slow for a master MythTV box? Also, what is
the lowest end video card that I could use before I start seeing
