[quote name='pop311']Wait, so is it true that you point at the sensor bar, and NOT the TV?[/quote]
Yes, you point at the sensor bar. You choose a basic setting that adjusts between putting the sensor bar under or on top of the TV screen.
EDIT: Direct aiming and 1-to-1 translation of where your wiimote is pointing really isn't desireable for anything but light gun games (which would probably need to be calibrated at start up). As long as there is a cursor on screen to relate to, pointing at the sensor bar allows for scalability of TV screen sizes. Imagine playing 4-player Red Steel on a small TV set if you actually had to aim at the TV.
