If you render a film at 1920x816 at 24p and tell your DVD software to interpret it as such, the viewer's DVD player will take care of the rest. Their player will add letterboxing as needed, as well as perform pulldown as needed
Exactly. The player at the end will determine whether or not black bars will need to be inserted.
Picture the screen shots above but without the horizontal borders. There is no reason to have them in screen shots. But they are there because they are "baked in" already.
Now imagine a windowed player (VLC or even vimeo.com)- in the player, the borders of the window are the borders of the video. But full screen it, and it will insert a black background where the aspect ratio does not match your monitor. But the way your video is set up now, it will have black borders even in the window. And if someone has some magical display that happens to be the exact dimensions of this video frame (I don't think they make one, but who knows what will come out in the future), it will be awkward to view it because the video doesn't actually match the size of the frame. It has been extended for black borders.
Sorry if I'm repeating myself here, but I'm trying to make sure it makes sense. Baking in black borders might give the desired effect in your personal viewing situation, but it is just a bad practice to have.
