If the Wega has the anamorphic squeeze feature, then you'll get a proper looking display from an anamorphic disc in either 16:9 or 4:3 setting. In 16:9 the TV is doing the squeeze, and in 4:3 the DVD player is converting the anamorphic signal to matted letterbox, and the TV doesn't squeeze. However, if you look closely, the image you get with the DVD set to 16:9 should be sharper because it has more vertical linesin the same height than the matted letterbox image.
