You realize the Saturn already has an S-Video cable right?

If you have the skill, the best thing to do is to tap the lines that lead straight to the custom A/V port. You can also trace the known pinout back to the source encoder if you really want, but really tapping the video and audio outputs anywhere on that particular PCB trace should be fine. There's no need to go straight to the chip, especially since it's less risky to ruin a connector than it is to ruin a whole encoder.
