You got it Ray. Just go into the DVD menu; look for "Audio," "Setup," "Language," or combinations thereof; select DTS (if available); and that's it. I'm always surprised to find audio choices in a menu entitled "Language." They hide the audio setup in some strange menus sometimes.
I don't know how your Denon works, but my Onkyo has a selectable display, and one of the selections shows the audio format that is playing. I use that one regularly, so it confirms that I'm hearing DD, or DTS, or stereo, or PLII, or whatever.
