Thanks Chessero, and yes I am using the digital out using fiber optics cable. I think the one that fixed the problem is the TVS settings of my DVD player (which is weird as this settings is applicable only if you are using RCA out)anyway I just turned it off and the DD-EX and DTS discrete works. Now I have to figure out the problem on DTS Matrix, can you give me the exact settings on your onkyo with re to this so I can compare it with mine when you get back home and have a chance to check your settings. Thanks again chessero, I really appreciate all your help......I send an email to onkyo support and all the stupid answer they gave me was " Go to Setup menu # 3 and change the Surround speaker settings to L/R+Back" duh!!!
