Chess I checked the on-line manual for the Panasonic DVD CP72. It's at
http://service.us.panasonic.com/OPERMANPDF/DVDCP72.PDF
Under the player's Audio menu, there apparently are settings for Dolby Digital and DTS bistream/PCM, plus a master setting for Digital Audio on/off.
It says the DD factory preset is bistream (not PCM), but DTS is preset to PCM. In theory if digital out was enabled and you play a DVD-A with DD 5.1, you should get DD 5.1 signals on your receiver. Virtually all DVD-As have DD 5.1. However you might have to manually select this when playing the DVD-A, similar to a DVD movie.
