With the projector in my apartment, I have a VGA cable and an S-Video cable running as inputs. However, my Playstation2 cable only has composite video output. It turns out that composite can be hacked into s-video fairly easily. By running the composite video signal to both the brightness and color parts of the s-video you get a usable video feed. It’s not great quality, but it’s better than nothing. I also managed to find a Playstation2 cable that had s-video out, so it’s no longer an issue, but for a while I needed a solution.
