I've decided to upgrade my capture card before continuing with this. If anybody can give me some links to some good capture cards I'd appreciate it. I'm also looking for advice on external comb filters. This is alien territory for me. It seems like Faroudja makes some good ones? Apparently there isn't anything that has ever exceeded the X0's comb filter as evidenced here?
EDIT: check page 2/post#43 & 44 if you are interested in that link.
