I have taken snapshots of the original into photoshop and followed G-Force's resizing step-by-step. He is removing the borders so they do not shake after the stabilization and cropping into the picture on the top and bottom to remove that nasty faint line (technical term is?) that is running by the black border top and bottom, which is great, but I am virtually certain that the cropping and resizing does not take NAB into account.

For an anamorphic 704x480 DVD, I would change resizing line to:

Spline16Resize(720,384).Crop(8,14,8,-10,align=true).AddBorders(0,58,0,58)

This might be a tiny bit faster, before the resizing stage, as the image being processed is a tiny bit smaller, and it would avoid the need for horizontal resizing. Alternatively, if you must author a 720x480 DVD you could make the resizing line:

Spline16Resize(720,384).Crop(0,14,0,-10,align=true).AddBorders(0,58,0,60)

Actually, DE, if the Anti-Aliasing filter is a line doubler and there has to be a vertical resize anyway, one might as well make this anamorphic, do you not think?
