I bought the 2-disc OOP dvd R2 with the matrix DTS-ES sound along with the making-of huuuuge book for £10 off eBay!

that's a shame - i've noticed most of my 6.1 dvds are matrixed (according to dvdprofiler) I thought I was getting the good stuff too - mind you doesn't sound too shabby

Can I say I'm glad that question was asked. I like learning more about Home Theatre and those little things you don't notice when you're operating your Home Theatre system. Sadly, I don't have a 6.1 or 7.1 receiver. I am happy with my 5.1 though. Maybe someday when I have my own place, I'll definitely have a dedicated room, big enough, and soundproof for a 6.1 or above system.

Discrete means that it has a dedicated sixth channel, whereas matrix means that the sixth channel is extrapolated from the read surround channels. Dolby Digital 5.1 EX is a matrix '6.1' system (i.e. it's not true 6.1), whereas DTS can be either matrix or discrete (but it is usually written as 6.1 regardless).

Technically, anyone referring to Dolby Digital 6.1 EX is wrong, because it isn't six discrete channels of audio (think along the lines of Pro-Logic). DTS is more of a grey area, it should be 5.1 for matrix and 6.1 for discrete, but the distinction is hardly ever made.
