I hope that makes sense, because I know I'm not communicating this in the correct technical terminology.

I think the problem is that 720 x 480 is 16:10 aspect ratio, whereas monitor resolutions traditionally work from a 4:3 (16:12) ratio, hence the "squishing effect" you noticed which has been eliminated by scaling it to 640 x 480 (16:12 aspect ratio, a.k.a. 4:3).
And now to wait the obligatory minute and a half for someone to come out of the woodwork and prove me wrong. Life: If you're not being kicked when you're down, you're probably dead.
