You can't.
Don't recompress the MP4 (or whatever "converting your material to avi cropping and decoding it mp4" means). Take the source and compress that properly this time. If you need help, PM me.

Thanks for your good will but help is no longer needed Leo,
changing the ratio to "Fully Expanded" helped with my project.

if the only thing wrong is the aspect ratio and you really want to avoid extra work, and you're not worried about wide functionality (in dvd players, etc), you can just change the pixel aspect ratio and it'll save without quality loss/recompression
it's not widely supported beyond the major software players though, or very unreliably
