I mostly agree, but there are some real issues. . .

1. it depends on which device has the better deinterlacer. If the DVD is better, output 480P, if the Projector is better . . . use 480i and let the projector do it. . . but there are even some issues here.
1a. If the deinterlacers are about the same, theoretically the DVD would be better, provided it follows the usual convention of processing entirely in the digital domain before outputting 480P. Otherwise, the the signal in converted to analogue, sent to the projector and (assuming a digital projector [sorry Mr. Kloss]) doubled and reconverted (actually reverse that, but the steps are the same). This used to be a greater problem than it is now, but many people can still see the difference.
1b. On many projectors, either VGA in or DVI in will bypass the doubler. And the advice is, if you got either of those inputs and your DVD player has the output, use it!

2. Most people change players more often than projectors. The player is, therefore, likely (not certain, just likely) to have the better deinterlacer.

Basically, 480p on a player is not an horrendous expense item. And it is switchable. Try it both ways and stick with what is the better image. Once again, projector central has an excellent article on the subject. Just in the interest of full disclosure, in my case, the player trumps the projector cleanly, but I have VGA out.

Oh, as an aside, all projectors were NOT built with deinterlacers. I refer you to the afore mentioned Henry Kloss and the Novabeam (ancient history, I know, but there are others, much more recent).
