DThiel:
Go take a look at the review of the Bravo D1 in the October (I think) Widescreen Review. In that review, there is a discussion of the relative merits of upscaled DVI output for various display technologies.
I considered both these players as well and decided on the D1 because of the 931's black crush and lack of aspect ratio control for older DVDs. Although some folks have had problems with the D1 (the D2 is supposed to be shipping in March @ $249 list price), mine has been fine.
I agree with MasterWick (and Widescreen Review

) that the benefits of DVI alone for your set will likely be minimal. The scaling issue, however, may provide some PQ enhancement since your display will display 480p and 1080i natively.
I'm sorry I can't be more help with this aspect - I have a DLP and its native resolution is 720p, so everything gets scaled to that resolution whether the TV does it or the DVD player does it. I am not enough of a techie to explain the signal path differences, but the D1 outputing 720p looks better on my set than letting the DLP scale a 480i image to 720p. My guess is that the compatibility between chips in the D1 is better than the compatibility between the D1 and the DLP.
