Spline36Resize(720,384).Crop(8,14,-8,-10,align=true).AddBorders(0,60,0,60)
or
Spline36Resize(720,384).Crop(8,14,-8,-10,align=true).AddBorders(8,60,8,60)
The first would give you a 704x480 DVD, and the second, a 720x480 one.
EDIT: I have deleted the third option. It was wrong: I overlooked something.
I prefer the first option.
