I have WinTV running with a PVR-250 card. The source is from my cable box, which is a bit dirty (noise, mainly). Overall WinTV's PQ doesn't compare badly with what I get from my HDTV when I feed it the cable signal via RF and let it demodulate on its own, but it doesn't look good enough to be a substitute. When viewing at full screen, I see too much pixelation, especially when there's movement. What sort of filters/software would you recommend with WinTV (or to replace WinTV) when using a PVR-250 card? I've heard of Snapstream, but I'm not sure that's quite what I need. Also, I installed ffdshow and tried tinkering with it, but couldn't see any difference in the WinTV output.
