Hmm, well, my TV does have a DVI input, too, and that input DOES accept
2 RCA connectors. To use it, I'd have to put a reasonable video card in
the AGP slot and use software decoding, as you point out, but then I'd
have audio via the sound card.

Of course, if I did that, wouldn't I have to buy another sound card in
order to capture/listen to the audio from the second tuner card? Or
could I get by with a single sound card? It's not completely clear to me
when exactly multiple sound cards are required.
