No huge reason why it wouldn't, s-video is just a high res b&w signal, 
with the color subcarrier on a separate conductor so they are never 
mixed. Once mixed, it takes very tightly tuned comb filters based on 
precision delay lines to separate them again, and lots of the resolution 
is lost in the process. But because the coco's outputs are not 
interlaced, the comb filter doesn't work, but the simple one in most 
tv's still kills the resolution.  s-video is not high def, but still 
noticeably better than composite.
