A common misconception - "Digital good", "Analog bad". (Or at least "Digital
better") It simply isn't the case.
Digital has yet to truly match the qualities of 35mm or 70mm film. No electronic instrument can match the sound of a first-rate piano or violin.
Digital and analog are simply two methods of recording and delivering data and have no affect on the quality of the data itself. (Shakespeare wrote
King Lear with a quill pen - analog. Whoever wrote
Ishtar used a computer and a scriptwriting program.

The defense rests.)
And by the time it gets to your speakers (and hence your ears) it has been converted to analog. We can't hear or see digital. (Unless you like looking at a
Matrix-like screenful of 1s and 0s.)
In the case of the 6.1 analog outputs the DVD player does the digital-to-analog conversion and the receiver simply amplifies the analog signal and sends it to the speakers. In the case of the digital outputs, the DVD player sends the 5.1 or 7.1 channel digital signal to the receiver, which then does its own digital-to-audio conversion and sends the result to the speakers. It is true that some DACs are better than others, and the one in your player may not be as good as the one in your receiver, but you have no real way to test that. And if you have an older receiver and a brand-new Blu Ray or HD-DVD player, odds are the DACs are comparable or that the edge goes to the players.

| You are correct. For some unknown reason, the analog inputs were factory set 4db lower than the other inputs. |
I have a feeling that when these things were designed the assumption was that the incoming signal would already be amplified to some degree, hence the need to lower the input volume. In practice this hasn't turned out to be the case.
