Don't confuse pixel ratios with aspect ratios.  The two are different
because when standard definition material is digitized it usually uses
non-square pixels.  720x480 is what's usually used for 4:3 broadcasts.
 If the pixels were square, it would be 640x480.  Modern LCD's all
have square pixels natively, but with CRT's the definition of pixels
in the horizontal direction is a little fuzzy.

But in the end, yes, it just works more or less automatically.  If
there's an aspect ratio mismatch, most systems offer a way to adjust
that manually.

I usually try to make my stuff last a little longer than that, but you
circumstances may be different.
