The A-DEP mode is designed to help produce photos where everything in the frame is in sharp focus. The camera analyzes everything in the frame and sets an aperture to get the maximum depth of field, then sets the shutter speed to properly expose your shot. However, the shutter speed it selects may be too slow to handhold. If the camera can't get an acceptable exposure it will change the aperture and disregard the DoF calculation!!. Also as soon as you turn on Live View or Flash (to get some fill-in light) the camera stops calculating the depth of field. All in all, I don't think there are many instances where this mode is going to be useful to you.
So as others have suggested, use AV or full manual mode and for landscape shots, focus about a third of the way into the shot and you should achieve the same or better results than the A-DEP mode.
