On HDTVs that have a "built in line-doubler" (take an interlaced image and upgrade it to 480p), does that work with videogame signals or only TV broadcasts? If it works with videogames, how is the quality? For example, if you have a Gamecube hooked up with component cable, and don't hold B for the progressive scan mode, and instead have the line doubler on, wouldn't it look the same as if the Gamecube was running in true progressive scan?

I don't have a home neo, but based on my other systems, everything that is not progressive looks a little nicer with line-doubling and low sharpness. To those who say HDTV makes 2-D look blocky, I say turn down the sharpness. The line doubler just performs operations on whatever signal comes into the TV, it doesn't know where that signal is coming from. So, no matter what you hooked up to the inputs, if the line-doubler is on it'll go to work on it.
As for progressive scan, it's a ton clearer than just line-doubling for anything well detailed.
Progressive scan runs at least at 640x480 resolution, whereas line-doubling tries to just fill in the blank spaces where the scan-lines would normally be located on a normal TV. It's as if they were just painting the scanlines in a pattern that blends in well with the current frame when line-doubling. It's not the actual data that belongs in that position so it'll result in a blurrier picture and it'll "preserve" most of the jaggies that you'd see on a normal TV. A de-interlacer might give very close results to getting real 480P input, but good ones are very pricey. Progressive won't have any jaggies due to interlacing, but it might have still have some due to poor anti-aliasing in the system or in-game effects like "Cell Shading", which actually makes the edges of a character stand out more. That sort of thing is just inherent to the game system and is not a flaw in the HDTV.
Also, certain games, might look alright without progressive scan, but anything with textures specifically made for 640x480 will likely suffer from a noticeably less detailed picture. In short, if you can do progressive scan when playing a game, there's no reason not to do so.
