TVs. In this situation, the image will not look right when 
displayed in 16:9 mode. In this situation, please try to use 
the 4:3 mode to view the DVD. If the content is not 4:3, 
there will be black bars around the image in 16:9 display. 
For this type of content, you can use LBX mode to fill the 
image on the 16:9 display.
