yes. You're magnifying a relatively low resolution image.

yes. Not as much magnification on the relatively low-resolution image.

yes. It should be fuzzy. And is. Not sure what the question is.

yes. reducing resolution means increasing the size of the pixels to
fit the display.

Place a picture on a photo-copier and blow it up 150%. It will look
fuzzy. That's just the way it is. Again, you seem to have explained
it all. Not sure what the question is.

I have the same system. your s-video should give a slightly better
picture than your component. Not sure what "a mess" looks like.
