You input.mpg seems to be in the PAL format (720x576). 720x480 is for NTSC. You should create a new project and modify its properties (menu Settings->Format). Use 720x576 and leave the "Aspect ratio Auto" toggle on. Changing the format of the project you already saved won't change the format of the material already put in place on the timeline. Changes apply to newly inserted material.
