@sugargenius:
Not having seen your source, my best guess from your description would be:
1. The source is "480p DVD" with movie content, hence it is most probably an NTSC DVD with DAR 16:9
2. All DVD video is anamorphic by the DVD standard, there is no "non-anamorphic 480p DVD"
3. As the content seems to be a movie (The Mask) it is most likely progressive video
4. According to IMDB the movie has an aspect ratio of 1.85. Assuming 1. is true, one would expect a frame size of 720x480 with top and bottom black bars of about 10 pixels each.
After cropping, the cropped frame without borders has a size of 720x(480-20) = 720x460. It is still anamorphic with a PAR (Pixel Aspect Ratio) of 32:27=1.1852 (or a value close to it, acc. DVD or mpeg2 spec.).
5. 720x460 can be horizontally resized to 854x460 or vertically to 720x388 for square pixels (PAR 1:1) => 854/460=720/388=1.85.

Above explains the basic steps (independent of any GUI) based on some assumptions(!) about your source. (MeGUI may round a bit differently due to mod constraints.)
For better advice you would have to upload a sample.
