The author of the review linked in the first reply to this thread writes the following:

For whatever reason, mainstream manufacturers of DVD players have been unable to recognize that DVI output would be a highly desirable feature on a DVD player.

Well, I suspect the reason is rather simple. They don't want to get their collective asses sued by the MPAA nor the studios for selling a device that comes set up to defeat Macrovision protection, which only works at 480 (i or P). Sure, you'll need a connecting device that takes the DVI input and can pass it back out to an analog output such as S-VIDEO. And, they could restrict the output to 480, something Bravo seems to not have done.

A digital signal out of a DVD player is a rather big thing and happens to be one of the major stumbling blocks for the release of higher definition DVD into the mainstream.
