I'll try to explain the way I see it (I'm in no way any type of expert). The difference is that the siganl is sent in a digital format with true 6 channel seperation. The 5 is for the Front Left, Centre, Front Right, Surround Rear and Surround Left (left & right rears). The .1 is for the subwoofer out which is not amplified so that's where the .1 comes into play. The sub needs its' own power as in a powered sub. A DVD player with this decoder, or an A/V receiver with this decoder will decipher the signal from the DVD player if a digital cable is used (coax or optical). Make sense now?

The .1 channel is labelled like that because it is has only about one tenth of the frequency range as the others (it's actually 20-120Hz vs. 20-20000Hz).

As well, Dolby ProLogic can be digital. DD5.1 is six discrete channels while DD2.0 is two discrete channels which can be matrixed with two other channels (center and rear) to give 4 channel ProLogic.
