Okay cheesero...my dvd player model is Sony DVP-NS700P. I checked my audio settings and my DD and DTS are set to DD and on respectively. Anyway I play around with some of my settings and was able to run a successfull test tone using the Star Wars episode 1 dvd THX audio test. The dvd settings that I made and work is the TVS (TV Surround) which is applicable only if using the DVD RCA L/R output which in my case I am using digital output using fiber optics as my medium. Anyway I turned off this settings and now it works.

There's only one thing left that didn't work, using the DTS 6.1 Matrix speaker balance test of S&V calibration DVD which I am experiencing same problem. But for DTS 6.1 Discrete speaker balance test, it's working as expected. Is there any chance you have tried this test and experience same problem? Oh btw, the DD 6.1 speaker balance test works fine already.

Thanks,
Sam
