Hi everyone, thanks for reading. I guess this falls into the "hardware" section. I'm looking for some kind of video capure card or USB device. I don't want anything fancy. What Im trying to do, is take an old video game system, like a playstation or sega saturn, and plug them into my computer via RCA(the red, yellow, and white plugs). After plugging in said old school video game system, I'd like them to show up on my monitor, so that I can take screenshots of the games. Some of the stuff I found could do stuff like pick up TV channels, and even record your tv shows while you were away. Thats way too complicated for what m trying to accomplish. All I really need is: plug in with RCA, show up on monitor, take screenshot.

A friend of mine recommended an all-in-wonder card by ATI, but as far as I understand, the all-in-wonder cards replace your graphics card. I've got a good graphics card now, and would like to keep it. I'd like to just get a PCI card or usb device or something. I also found a USB device that had RCA plugs, and would record videos. However, it couldn't take screenshots... If I can't find anything else that works, I could try that out, and see if I can take a single frame out of the video, or even do a screen-dump while the video is playing...
Any ideas?
