Specifies the display mode for DVD video playback, controlling how the video content is displayed based on different aspect ratios and presentation methods.

public enum DVDDisplayMode

Fields

Default = 0

Uses the default display mode as determined by the DVD content and display device.

In this mode, the system automatically selects the most appropriate display method based on the DVD's native aspect ratio and the current display configuration. This is typically the recommended setting for most playback scenarios.

Mode16X9 = 1

Forces display in 16:9 widescreen aspect ratio.

This mode displays the video in a 16:9 aspect ratio regardless of the original content's aspect ratio. For native 16:9 content, this displays the video correctly. For 4:3 content, this may result in horizontal stretching to fill the widescreen format.

Use this mode when you want to ensure widescreen presentation on 16:9 displays, particularly for content that was authored in widescreen format.

Mode4X3Panscan = 2

Displays content in 4:3 aspect ratio using pan and scan technique.

Pan and scan is a method used to adjust widescreen content to fit a 4:3 display by cropping the sides of the image and potentially panning across the frame to follow the action. This preserves the full height of the image but loses content from the sides.

This mode is useful when playing widescreen content on standard 4:3 displays where you want to avoid black bars but are willing to sacrifice some of the horizontal image content.

Mode4X3Letterbox = 3

Displays content in 4:3 aspect ratio using letterbox format.

Letterboxing preserves the original widescreen aspect ratio when displaying on a 4:3 screen by adding black bars at the top and bottom of the image. This ensures that the entire original image is visible, though at a reduced size.

This mode is preferred when you want to maintain the director's intended framing and see the complete widescreen image on a 4:3 display, accepting the presence of black bars as a trade-off.

Remarks

The DVD display mode determines how video content with specific aspect ratios is presented on displays that may have different aspect ratios. This is particularly important for preserving the intended viewing experience when playing DVDs that were authored for different display formats.

DVD content typically comes in two main aspect ratios: 4:3 (standard definition) and 16:9 (widescreen). The display mode settings allow proper presentation of this content on various display devices.
