Krell Showcase set up help for newbie

I am a newbie and this will be my first HT. My installer cannot come for a couple of weeks and I got all my gear. So I installed the gear my self. Well, connected all the wires anyway. The issue I think I am having is that I am stuck in Dolby Pro Logic II.
I do not think the Showcase is auto-detecting Dolby Digital 5.1. After selecting the Dolby Digital 5.1 in the DVD set up options, the front panel display still says Dolby Pro Logic II. I set up the DVD in the Configure Devices menu to default to Dolby Digital 5.1. Never the less, it always defaults to Dolby Pro Logic II. The display always says Dolby Pro Logic II and the LCD for Dolby Pro Logic II is always lit. The manual say to press M2, I keep pressing it and the only options it gives me is different variations of Dolby Pro Logic II (Dolby Pro Logic II + THX, Dolby Pro Logic II Movie, etc.) and the Krell music modes.

The same thing is happening with the CD setup - always defaulting to Dolby Pro Logic II Movie despite its default to Dolby Digital 2.0. The only way I can listen to 2 channels is by pressing the Stereo button on the front panel.

DTS is auto-detecting just fine. The front panel display says DTS 5.1 after selecting it in the DVD set up options.

How do I know a movie is playing in Dolby Digital 5.1 and not Dolby Pro Logic II?

Thanks in advance for any help,
Cap
