I have now had too tell 3 people this, that owned dolby digital/dts recievers, 5 speakers and sub, that were simply using the 2 channel rca outs from the dvd player to the inputs on the reciever thinking they were getting true discrete dd/dts sound. I informed each they were not getting true discrete sound, but just dpl or dpl 2 (which can still sound good). I told each to get a optical or coax cable and after the switch., they could not believe the night and day diff! Anyone else come accross this? Thank god for people like us!!!
