I'm not sure anyone answered the question. I'm not sure I can either. However, it appears different receivers process 2-channel/stereo differently. Out of my dvd player, I use one BEL-the wire as a digital coax connection. This sends the signal for all digital including the "stereo" setting on my B&K. The center channel provides sound in this setting. However, when I switch to "direct" from the stereo setting, only the R/L speakers provide sound from the separate pair of BEL-the wire I/C's connected from/to audio out (dvd) to audio in (receiver), in essence an analog (although since cd and dvd are digital formats, analog may not be the correct term) signal. Maybe this helps, maybe I've just added to the confusion.
