Ok, I have Power DVD. I played Rush Hour 2 in DTS. Sounded great. Got 4.1 audio. And I tried my MPEG Video CD files. Prologic 2 was workign great with those. But, when I play a MUSIC file in Power DVD, why is the left and center info coming mostly out of the front left speaker and the right infomation coming out of the left REAR speaker only? This ain't supposed to happen. Oh, and another problem. When I play music in winamp, the sound comes out of all 4 speakers, including mono sounds. On a Prologic system, this don't happen. Only OUT OF PHASE info comes out of the back. How do I fix this?
