The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
However, this causes the 4:3 image not to be what the director intended the audience to see, and sometimes boom mics, edited out of the shot when the picture is matted, can be visible.

Unlike standard DVD-Video recordings, the aspect ratio (4:3 or 16:9) is contained in the .VRO file itself as part of the video stream. Thus DVD-VR supports mixed format presentations within a single .VRO file. Contrast DVD-Video where the aspect ratio is coded into the accompanying .IFO file and thus a single .
