Basically ive bought a pioneer DVR-3100, and i want to plug up an old surround sound system ive got to it, problem is it needs to be connected by both the optical output and coaxial but the player doesnt have a coaxial connection. Does anyone know of an adapter that will plug into the existing connections in the back of the player so i can plug the coaxial into it.
the connections available to me are as follows, so the adapter would have to fit one of these.

Input 1 SCART (AV connector2)
2 RCA (Audio/Video) (front: 1)
2 S-Video (front: 1)

Output 1 SCART (AV connector 1)
RGB Output
1 RCA (Audio/Video)
1 S-Video
Optical Digital Audio

So if its possible is the first thing, then if so where to purchase it preferably in UK. Any help appreciated
