Depends on what type of "converter" he is using, but I agree this is  
the root of the problem.

Be aware that the adapter supplied with nVidia cards is *not* a  
converter, it is simply ti allow you to access the composite signal  
from the S-Video-type connector.

But like I said, if his target is a composite input, there is no  
reason to fool with S-Video at all.
