You're doing fine working through the issues yourself. I used to try to overexplain everything, but now it seems like people understand better if they make the connections themselves. Let me just add this -- the pixels are not square, and never have been. That's the difference.
640x480 would be 4:3 in square pixels, yes. But 720x480 is higher resolution -- an extra 80 pixels of resolution. Just because the pixels aren't square, does that matter? As long as the device you're displaying it on has similarly-shaped pixels, then you get native resolution.
And here's the kicker -- CRT televisions don't have pixels at all, anyway!
