Is there a reason you need to resize the footage to 640x480 specifically?
Look at the footage in DVD2AVI/DGIndex. If you see big black letterboxing, then you should crop it out. Otherwise, shoot THIS mother!@#$er you don't need to do any cropping just yet.
There's nothing stopping you from doing all your editing at the native DVD resolution of 720x480 if you want to. It's only when you're finished and you get to the encoding process that you really have to worry about resizing.
(Except if you're adding your own images to the video. Then you have to make sure their PAR matches the PAR of your video source.)
