Looking for a TV Tuner/Capture Card that takes Component (Y/Pb/Pr) input

[yukichigai]

I've been trying to lay my hands on some kind of component video capture card so I can exploit the new DirecTV HD receiver I have access to. The only thing I've been able to find is a Leadtek card (WinFast PVR3000 Deluxe) that has Component Input capable of handling 480i. Honestly though, if that's all it can do, what's the point? (Well, except that's some fine-looking 480i you'll get) I've poked around Newegg, Amazon, even a few manufacturer sites, all to no avail. I know they're out there, somewhere, I just don't know where exactly.
