For Dolby Digital and dts decoding, the DVD player should be connected to the RSX 1065 via either a coaxial digital or optical cable to one of the 5 digital inputs on the RSX 1065.  After physically connecting the cable, the digital input also needs to be assigned to a particular input on the receiver.  In this case, the digital input must be assigned to the input the DVD player’s video is connected to.  To do this, access the OSD and select the INPUT SETUP menu from the Main Menu.  There, the INPUT can be changed from Analog to the appropriate digital input.
