Video capture methods for Vista Ultimate 64-bit? (USB, capture card, etc)

Hi and thanks for looking. I'm about ready to give up on this. See, I want to record standard quality Wii gameplay videos on my Vista Ultimate 64-bit PC. I have Wii composite cables, S-video composite cables, and component cables. I'm looking for a device supported by Vista 64-bit that can capture Wii gameplay videos, be it an external USB-based device or a tv tuner / capture card. I can't find anything though; a few things out there (Gamebridge, Kworld DVD Maker, EasyCap) don't work on Vista 64. If any of you could help, I would really appreciate it. Otherwise that's it; no Brawl videos for me :(

PS - I wouldn't want to use a DVD recorder or something similar; hopefully it doesn't come to that.

...yay, found one...for Australia:

Anyone? Video capture on Vista 64-bit? Yeah?
