ffmpegX failing to convert .MOV to .avi mpeg4…?

On my MacBook I dropped in a .MOV file into ffmpegX, selected DivX AVI and clicked Encode… with no luck.

The error message I kept getting finished with:

Movie-Aspect is undefined – no prescaling applied.”

The solution was to go into Options and change Scaling method from Fast Bilinear to Bilinear.

Plenty more discussion on this here:
