I have the Sony S500D DVD player which says it will pass DTS through to my Sony 935 receiver, has anyone proven that this works?

Also, can someone tell me if I only need to connect the AC-3 coax, or the TOS-LINK, or the 5.1 inputs from my DVD to my Sony 935 receiver? Do I only need one of these, or more than one? My receiver will allow me to connect all of them, but if I only need one, which one is best?

Can I make my own S-link cables? Does anyone have the data on it or should I use my ohm meter and figure it out myself? I thought I would get S-link cables with all of my Sony gear, but no go.

About the Sony CX350 300 disc Cd Changer, there isn't an S-link on it, but there is a connection marked A control, or A1 control, did Sony change this on newer models?

If you can't answer all of these questions, answer just what you know about. Thanks.
