picture	Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables most standard
	screen TVs to display a full screen picture when the DCX set-top is tuned to a 4:3 program.
	Set the TV TYPE to 4:3 Pan-Scan. This enables the DCX set-top to remove the black bars
	above and below the picture when possible.
	Some SD programs are broadcast in the letterbox format with black bars above and below

	This may occur on a 16:9 TV if the active video for an SD broadcast is in letterbox format.
	To confirm, wait for a commercial or look for a graphic, such as a network logo. If the
	commercial fills the screen from top to bottom, or the graphic appears below the active
	video, the program is being letterboxed by the broadcaster. You can minimize this by
	activating the zoom feature on the TV.
	A broadcaster may include black bars on either side of a wide screen broadcast. This is
	called a “hybrid” aspect ratio and results in a black border surrounding the video on a 4:3
	TV. Because this is part of the broadcast, the DCX set-top cannot correct the video. You
	may be able to minimize the border using the zoom feature on the TV.
