OK, I'm not a SACD expert nor do I even own a SACD (maybe soon). But I do know how to do hookups. To be honest, unless I'm missing something, you do not need all those connections. All you need is a video feed and an audio feed. Use the optical cable since you have one and disconnect all other audio cables. Then connect the S-Video cable from the SACD/DVD player to the S-Video connection on the receiver or directly to the TV. I have mine running to my receiver for video switching. If you connect to your recevier then run another S-Video cable from the monitor out on your receiver to the TV. Bingo all done with connections. The optical is for audio and the S-Video is for video. Now select your SACD on the recevier and then go to the setup menus and assign whichever optical connection you used for this device. On the SACD player menu setup make sure you pick something that might say SPDIF RAW since you are sending audio via digital cable. Lastly, test everything and see that you have both video and audio. NOTE: the 6 RCA connections are for an analog connection to your recevier. You don't need to connect this since you are using digital/optical cable. The 2 RCA connections are for stereo analog audio connection. Again you dont need because your using the digital/optical cable. And since your using the S-Video instead of the composite (yellow RCA cable) you dont need this one either. Hope this helps and provides a little insight into what all those connections are for. Why do they put them all on there your probably asking yourself. Well, some people do not have 5.1 receivers and have only stereo amps or receivers (i.e. two channels). People with these types of amps or receiver would use the two RCA jacks to connect to there equipment. It goes on and on put I think you get the picture now.
