Do you know how to select DD on the AVR-2807, or better still to have it select DD or DPL automatically?
I'm still not sure you're understanding. You receiver is likely playing Dolby Digital, but you have the Dolby Pro Logic processing turned on, so that's what's in the display. You can confirm this by looking how many input channels there are. If there's 5.1 and the display says DPLIIx, then this is the case. If there are only left and right channels being input and it says DPLIIx in the display, then it's probably just a PCM stereo signal. Either way, if you want the raw signal played without processing, then you have to turn the processing off. I'm not with my Denon right now so my memory is fuzzy, but you either hit the "Direct/Stereo" button (to Direct) or the "Standard" button on the remote until you've cycled out of DPLII and DTSNeo:6 processing into nothingness.
There is no Dolby Pro Logic on a DVD... it is not a content and the receiver can't "sense" it anywhere. It is something that your receiver applies to a signal (Dolby, DTS, Stereo, whatever) to produce sound in 7 speakers.
The receiver is sticky... if you used Dolby Pro Logic processing on your last 5.1 Dolby Digital signal, then it will use it again on the next one until you turn it off.
