BD-Rebuilder Woes backing up Dark Knight

I insert the movie, and it starts right at the beginning of the film. I too, thought it was the 'straight to the movie' behaviour, but the Disc Menu function is disabled, and doesn't show up on my computer, either. It certainly does on the original discs... I' ll fiddle around with it later tonight, and try some other flicks. Heh, maybe 'Movie Only' will give me menus. Or perhaps a config file doesn't match what's selected in the GUI. thanks.
