Yes. The Quadio layer on the disc plays at a low speed, but the stereo layer plays just fine. I hear all the speakers on the Quadio even if it is slow. I'm not yet at a point where I'll just get another copy and see if I had a bad one. New TVs seem to be turning to having their own external speaker systems, so using the tv as a menu may be causing issues. . . .We assume that when the menu is displayed on your TV, you've chosen Quad, but you only hear two LR speakers or more than four correct?
