Windows 7: IEEE 1394 Capture Card

I'm looking for a video capturing device to use for some of my gaming consoles (360, PS3, and retro). My current method is using my DVD recorder for these devices, and then ripping the DVD on my computer.

Is there a device out there for the PC that can capture at least Component video? S-Video support is fine too.

And from the capture cards I've seen on the market, they all use USB 2.0.
I'm very skeptical when it comes to USB and video-capturing, so is there a IEEE 1394b capture device, or will USB 2.0 suffice?

And even though this is a Windows forum, any chance of this hardware working on a Mac? Specifically, a MacMini?
