i want to connect an xbox up and though of having the svid into the amp under i think its the user1 input selection of sockets. Then use user1 output connections to connect an svid cable back to tv. ( Tv and amp/xbox are at opposite ends of room ) however this has no optical in which the xbox can utilise. down the left hand side there are a row of optical in's i can use the md/dat socket and select md/dat on the amp and hear the sound fine. however if, as above i have the picture going through a "user1" connection socket, how can i select both the sound and pic at same time ( the general idea ) if i select md/dat i'll get sound but no pic if i select "user 1" i'll get pic but no sound totally confused. its not like me not to figure a techie manual out in about 5 mins flat. this one is giving me a few probs though. Personally i don't think its very well written.
