Hi TIC,
I have only PCM digital connection out of my DVD player. My experience is that the player may choose Dolby 2.0 on its own. Forcing the audio format to Dolby 5.1 (the playere would show "Dolby 2.1") sounds better to me.
If the DVD player automatically chooses the format with most discrete channel (as the one described by jz), then there is no need to change anything after setting the digital format to PCM. Otherwise, I would double check to make sure Dolby 5.1 instead of Dolby 2.0 is used.
