While HDV and FHD video can rendered for Blu-ray media, the widespread
DVD can only playback SD video content.
HDV camcorders can during tape playback 1440x1080 anamorphic HDV
content, downconvert it to Widescreen Anamorphic 16:9 video.
Is it possible to get a Preset for DV(D) wide 16:9 video?

16:9 is the only widescreen aspect ratio natively supported by the DVD
format. Anamorphic DVD transfers store the information as 5:4 (PAL) or
3:2 (NTSC) square pixels, which is set to expand to either 16:9 or 4:3,
which the television or video player handles. For example, a PAL DVD
with a full frame image may contain a video resolution of 720×576 (5:4
ratio), but a video player software will stretch this to 1024×576 square
pixels with a 16:9 flag in order to recreate the correct aspect ratio.

DVD Video - Widescreen Anamorphic 16:9 16x9
A DVD labeled as "Widescreen Anamorphic" contains video that has the
same frame size in pixels as traditional fullscreen video, but uses
wider pixels. The shape of the pixels is called pixel aspect ratio and
is encoded in the video stream for a DVD player to correctly identify
the proportions of the video. If an anamorphic DVD video is played on
standard 4:3 television without adjustment, the image will look
horizontally squeezed.
Although currently there is no labeling standard, DVDs with content
originally produced in an aspect ratio wider than 1.33:1 are typically
labeled "Anamorphic Widescreen," "Enhanced for 16:9 televisions,"
"Enhanced for widescreen televisions," or similar. If not so labeled,
the DVD is intended for a 4:3 display ("fullscreen"), and will be
letterboxed or panned and scanned.
