I just added in a 6th speaker for the back, so I'm newe to this.
My receiver has a manual setting for Dolby EX and DTS ES Matrixed that I can put on pretty much any DVD, even if it's not flagged for EX or ES. So, this just means it's taking the back two channels and trying to create a 6th channel, right? Is that usually a good thing, or do you all find that it is better just to leave it alone?
Also, on Pirates of the Carribean, which is the better track to listen to: The Dolby EX, or the DTS Matrix? Usually I would guess DTS, but I'm not very familiar with DTS Matrix.
