So I received the TV2000 XP Expert card today and it's not bad at all. My current PC does a great job of capturing 720x480. I have an Athalon XP 1900+ with 1 gig of ram and a raptor drive. The hitch is, if I capture totally uncompressed AVI, nothing's wrong. But if I add they huffyuv codec, it captures...without frame drops BUT when I go to play it back in Vegas or Media Player it slows to a crawl during playback. I can compress it to something else and it's fine but intial playback is pretty much in slow motion. I'm guessing it's just too much for my PC for whatever reason.

Any ideas why the huffyuv codec would slow playback without dropping frames?
