Wondering what you fellow 6.1/7.1 system owners do for DD? Personally, for movies I like to force EX for everything because it seems more diffuse and enveloping. 5.1 seems a bit more directional to me, but this can be cool for concert dvds at times. I haven't actually messed matrixing DTS tracks yet...but most of what I have is DD. What's your preference? Go with what's flagged/encoded, or go with EX? PS Mods, not sure which forum I should post this in, please move it if I was in error. Thanks!
