I’ve got a Pinnacle video capture card for my PC that has both composite video and s-vhs in sockets and composite video and s-vhs out sockets.

Due to the stupid ‘tool free’ design of my PC’s case which involves holding pci cards in place with a nasty sliding plasic thingy, rather than a nice sensible screw, the card slops around a bit. Rather than faff around pluging cables into the card and risk moving it about, I’d like to get a breakout box that I could simply plug into the card to provide sockets to plug the video sources into. It would obviously need both composite video and s-vhs in and out sockets (Firewire would be great too as the card has this also, but I suspect that this is asking too much). Does such a thing exist? I’m having problems coming up with the right search terms to find what I’m looking for.
