The ATI Radeon in my dad's machine can take standard phono plugs (the red, white and yellow triple things) or a standard S-VHS plug for both input and output, in addition to the standard monitor video out. The audio is actually hooked up to the sound card though from the video card, since it's gonna be the sound card recording the sound. You can get SCART to phono/S-VHS adapters, if your video equipment uses SCART sockets.

You might be better off looking on sites which actually sell the products and give technical specs on these specialist video cards
