You get to one by going to "scene selection", going to part one and pressing "up"(or is it "left"?) and then enter; and the other by going to "episode selection", going to episode one and pressing "left"(or is it "up"?) and then enter.

You'll  know you have it "selected" when the "cursor" disappears. If that makes any sense...

... I can't remember which is which is which, so experiment.
