The indicators tell you the input signal the receiver "sees", not the output you have chosen. From what you said, I'd guess your receiver is getting a stereo signal from your DVD player.
This could be caused by a setting in your DVD player. Check to see that it is not set for PCM only. Typically, when they are, DVD players only send out a stereo signal. The specific terminology varies by model, but you should verify that DD and dts have been activated. Some players require you to activate them separately. Sometimes what you trying to turn on is called Bitstream or Raw.
If that isn't the issue, another thing to try might be cycling the Signal Sel button. Try manually setting the DVD input to Digital. Sometimes changing it manually works when Auto doesn't.
