If I connect a coaxial digital able from my DVD to my receiver, may I assume I must connect the digital out to the TV set otherwise there is no point in connecting digital coaxial from the DVD to the receiver? The problem with this is that my TV only has composite/S-Video. Could you clarify this issue.
Coaxial [Digital] is Audio. It is a stream of digital data that only contains audio. I can contain PCM, DTS or DD. This is usually an Orange RCA connector.
Though they use the same type of connector, they have nothing to do with each other and are not compatable with each other.
Your DD/DTS lights are not comming on because - 1). You MAY have to assign that particular digital jack to the device you are listening to (the DVD I assume). 2) using your receivers setup. You MAY have to tell your receiver to automaticly detect the digital audio when it is present for that input. That is also in your receivers setup. It will look like this:
DVD: Analog, PCM, DD, DTS, Auto.
You want AUTO.
Hope this helps.
