Might be useful to make a basic distinction.
While the AVR has capabilities for Dolby Digital and DTS, you do not get to select which one is in effect. That is decided by the signals coming into the AVR--the AVR dutifully decodes them. Those signals are a matter for the source unit to handle. And the source unit (cable/sat box, BD player) is in turn controlled by the nature of the source signals it is offered by the broadcast or disc in question.
For example, the HD cable box will typically offer a choice of DD bitstreams (can be 5.1 or 2.0), or 2-ch PCM. If you want 5.1 programs, set it to DD.
The BD player will output any codec supported on DVD and BD formats, and if connected to an agreeable AVR by HDMI, your AVR will have access to whatever the player can dish out. The disc maker decided which audio options to provide.
After that is settled, the question of surround decoding comes into play--and that decision is yours alone. Do you want stereo programs played in stereo? Then turn off all surround processing (Neo:6, PLII, etc). But if you want to hear surround sound from the stereo sources, use one of those modes.
