Superbit DVDs are a marketing tool used by Columbia Tristar.
The theory (which is sometimes, but not always, actually true) is this:
They are technically regular DVDs. So for compatibility reasons they work just like any other. However, the amount of digital compression is reduced. More data is used for the film. So, the visibility of compression artefacts is reduced.
It's achieved by limiting or doing away with, completely, the extra features, trailers, subtitles, alternate language dialogue tracks, commentaries and the like, and using the space saved for more data in the movie.
They mostly (or all?) have DTS audio as well as DD.
Some use better transfers of the film. A notable example of this is Spiderman 2, in which the PQ is vastly superior as it is almost completely devoid of the Edge Enhancement that the other versions "enjoy".
Separate names with a comma.
