I would double check on Sony community forum what people use.looks like you use one of the component inputs and possibly set to composite mode.

Its nearly 18 years since i used this setup so my memory is vague, but by the looks of the maplin connector, its a double ended unit with s-video socket at one end and composite phono socket at other. So it will act as a gender changer between two cables with plugs.

So yes, looks like it needs a composite cable - probably only needs to be a very short run, but that depends on cable quality.
