1) I cannot get the 5.1 layer of DSOTM to play, only the stereo version. However, for DVD-A disc it works fine. Any suggestions here? 2)Is there a way to switch from the DVD-A layer to the Dolby Digital or DTS for comparison sake. When I went back to the Music DSP (pro logic II), it wouldn't switch over to DTS/DD on any DVD Audio disc I have. Just for kicks: I have it setup with the 6 MCH outs, the 2 channel analog output, and the digital out. I went in to the setup and it walked me through it, so I don't know where to go from here.
