I agree 100%.
I only mentioned great in the context of his experience between 5.1 ans 2ch, not as to compared to bluray or DVD.
Sorry about the confusion.
As far as getting good 2ch matrix sound, I get good results with a Pioneer AVR and Dolby Pro Logic IIz.
Saved me the headache I was getting with my cable box.
Blurays are DTS Master HD or TrueHD only.
