The ATI all-in-wonder series of cards (including Radeon) can accept an S-video signal in, adjust the black level and contrast, and pass the signal out again. But the quality is too fuzzy for my eyes. Seems like they low-pass filter the signal. What PC-based video card does not cause this degradation? (It does not have to be the primary display card or even a display card at all, just under $300).
