1. This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is set to OFF. Adjust the setting to either 480i or 480p depending on the capabilities of your TV. 4:3 standard definition programming will then fill the screen. To do this, turn off the DVR and then press the "Menu" button on the DVR. Use your up and down arrows to choose "4:3 Override," and then use the right arrow to enable this selection.

2. This may occur on a 16:9 TV if the active video in a standard definition broadcast is broadcast 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 your TV. Note: Not all DHTVs have a zoom feature and zooming may only work with regular cable programming, not HDTV.

3. In some instances, broadcasters may include black bars on either side of a wide screen broadcast. This is referred to as “Hybrid” aspect ratio and, on a 4:3 TV, will result in a black border surrounding the video. Since this is part of the broadcast, the DCT5100 cannot correct the video. You may be able to minimize the border using your TV’s Zoom feature (see note above).
