OK, it sounds like the aspect of the wide DVD footage is distorted to
squeeze the 16:9 to (nearly) entirely fill the 4:3 frame. You said the
problem also appears in inigo, but I want to know if you played the
kdenlive project file or just the 16:9 DVD video file. Also, here are
some things to do to discover the source of the problem:

1.) Again, just playing the distorted file in inigo: inigo -profile
dv_pal some.mpg

2.) Play the file using ffplay; does it look correct?

3.) Send the output of 'inigo some.mpg -consumer westley'

4.) Send the output of 'ffmpeg -i some.mpg'
