I have a commercial DVD (The Quiet Man - Collectors Edition) that will play normally from the main menu, but if I stop the movie and begin playing again, it gives me the movie with commentary (the third audio track on the disc). This happens on 2 different set-top players.

I was unable to find anything in the help file that applied to my particular situation, but since I know next to nothing about DVD structures and commands, I may have overlooked something that would have pointed me in the right direction. How can I use DVDRP to have the disc go to the main menu every time the "Play" button is pressed on my players? In addition, is there a resource available on DVD structure that would help me as I learn to use DVDRP? Any assistance would be appreciated.
