no. the DVD has nothing to do with this.... the only possible explanation is that you did something wrong, but I'm not sure what
when you place the statues in correct order, the robot poster on the left of the shelf will disappear and a black hole will open. then you need to pick up the hand light (on the floor - down right). then you can step inside the hole. perhaps you don't have the hand light yet? (because it will not let you step inside if you don't have a light first since it's too dark in there).
