Hi Peruvian; OH I do listen to discrete dvd 5.1. Oh Yes. Pro-Logic 2 music is used to bring out those ques in a 2 channel track that are really there whether they were deliberately put there or not. In the era of quad, they were delibertely put there, but what quad needed in the era of quad was the type of surround systems we are using today with the DPL-2 music decoding. The good thing is that your current discrete 5.1 set-up can work well with DPL-2 music but it is necessary to do some tweaking on the dimension and width adjustments to get it to sound right. DPL-2 movie does not have those adjustments and just makes it "worthless" to use. I use the DPL-2 music mode to listen to two channel Dolby Surround movies that I still have on stereo tape. Many movies take on a rather awsome surround sound quality using this mode sounding "similar" to in some cases a D.D. 5.1 discrete EX sound track. Discrete gives a cleaner sound, but this matrix fig-a-ma-jig is not bad at all.
