Press the "Menu" button.
Go into the "Playback" menu.
You won't see it right away but there's a second screen you can scroll down to with one lonely little option...
Click "On" the "Overview" option.
Click on whatever other options you want in this menu as well, obviously, but you're probably looking for the "Overview" option. It always struck me odd this option is not enalbled by default, but it's not. Hope that helps.
