Is where we part company. You cannot achieve the same results with a upscale to infinite resolution. You cannot believe that your can sit closer and closer to an SD image (zoom in), as long as the distance is one which does not fully resolve the picture elements; that as long as you upscale the picture it will always be superior. A good upscaling algorithm will be finely tailored to go from one particular resolution to another. It also will hopefully do it's job in one pass. To say this algorithm will scale to infinity and always yield a superior picture (given the caveats to what is "superior" - that is able to be view at a bigger angle of view, i.e. "zoom in" - that we now agree on) is also hooey. A Gaussian blur, used iteration after iteration, will soon reach a point of diminishing return and that point is well before infinity. Unless those CSI's really did take a low-res traffic camera photo, blow up a small reflection off an eyeglass lens and get a 5 megapixel mugshot.
Think about it, Chris. Really think about it. It really is the absurd CSI scenario above that your "infinite resolution" statement is alluding to.
