is it possible to get a true 16:9 aspect ratio

[justinr1]

hi,
most of the movies I encode to vcd are divx movies that are about 640 * 272 ratio. I realize that this is anamorphic widescreen (the theatre version). I also know that you can make this video to full screen (without stretching) by picking no margin aspect ratio in TMPG ENC. Is there a way that you can crop the video when you put it in 16:9 letterbox or is this impossible with this program. All the movies I make are in 16:9 letterbox and come out a little strecthed. It's no big deal because the only time you realize the picture is stretched is when you notice a car in the movie. Nonetheless, I would still like to know if it is possible to crop my movie in the 16:9 mode like it is done in 4:3 mode so that the picture is not stretched. Thanks in advance for any help that you can give!!!!!!!!!!!!!!!!!!!1

just ad borders to the video this will keep the ratio and give a better picture also.
