OK, so to cut a long story short, I want to stream Gamecube games (composite cable/SCART output). To this end, I got a second hand Hauppauge HD PVR 2 Gaming Edition.

This has both an HDMI port, and an A/V input port. The latter was intended as a work around for the PS3's inability to transmit unencrypted HDMI, but a composite cable can be inserted in such a way that it still accepts the input. My second hand unit didn't come with the "Component A/V input cable", so I've had to order one from the Hauppage website (it seems to be something only they manufacture). It's been a couple of weeks, and I'm still waiting for it to arrive.

I was wondering if anyone knows if there's a way to hook up my Gamecube's composite cable to the A/V input with more easily found cables?
