Anamorphic movies are supposed to be vertically stretched. If your target is DVD, leave it alone, and set your DVD to anamorphic 16:9. The DVD player will crunch it back into its correct proportions when playing -- filling the screen if it's an HD TV set, letterboxed if it's an SD TV.
If you want the letterbox bars to be part of your image -- you would do this if you're anticipating that your target audience won't have a 16:9 device -- then put the movie file (or the anamorphic 16:9 sequence) into a
non-anamorphic sequence. (This part is in my FAQ article) This would apply a -33.33 Distort - Aspect Ratio crunch to the image.
