I actually made a cable that goes from the DIN on my C64 and C128 to an S-Video connector. It uses the chroma and luma from the Commodore, and connects to the S-video on an LCD TV. Works great! Here is a link to what I used for the C64, it has the pinouts for the S-video cable. If you know what the pinouts are on the Amiga, just match them up.
