I understand that when upscaling a DVD you are not really adding pixels, but apperently you can with Dolphin (messing with the polygins or something) and also in DVD's you can't just get extra realestate but you can in dolphin (because the information is there, just not visible)
That's only applicable for video streams, such as video DVDs or FMVs in the game, which are at that resolution already, and there's no way to get more detail out of them because it's already "hardcoded" at that resolution.
For games, it's completely different, the polygons don't have any hardcoded resolution, they're not a compressed video stream. It's the same as with PC games. That's for 3D games, and that's only applicable to the polys, the textures need filtering so they don't look like crap. 2D sprite games can't really be enhanced by larger resolutions, because just like the textures in 3D games, they are already at a "hardcoded" resolution, but you can still filter them. There's just no good way to filter 2D sprites in dolphin yet, such as 2xsai or something like that.
The Widescreen hack just shows whatever the devs didn't intend you to see at the sides of the screen, that's why sometimes you can see certain bugs at the edges, like dissapearing models, or models not appearing before getting to the 4:3 range of the screen. It doesn't happen with Wii games, because all the Wii games (I believe) have widescreen support.
Consider game DVDs as just common storage DVDs, because that's what they are.
