My setup is really simple, just as described above. I don't use TheaterTek + ffdshow, because my computer's processor can't handle it. I just use PowerDVD 6, which already kicks my Oppo's butt - so your setup should be better. But I have seen the light! FP and HTPC is the way to go (for now anyway).

I even tried comparing Call of Duty 2 on my setup with computer vs the Xbox 360, and the computer is definitely sharper (slower though...but that's just my old processor)

Next in line is an HD tuner card, the MyHD 130...and it's Valentine's Day tomorrow - I should buy me something, cause there's no one else I love more than myself! lol

Good luck with your HTPC build. Are you gonna use Windows MCE 2005?
