Maybe MLT, as used by kdenlive, is not detecting the widescreen. That
is the most plausible cause. You can check this yourself by running
'inigo' against the video file. Don't worry if it does not fill the
window or size the window to the video resolution--that's not
important here. What is important is whether it keeps the aspect
ratio. If inigo does not play it properly, then we have to figure
which codec your version of MLT is using. Well, you can do the
following and report your results:

$ inigo avformat:video-file

$ inigo libdv:video-file

libdv was the default in older MLT versions and avformat is the
default since mlt v0.2.4. The above let's you override the default and
explicitly use one.

Probably, it is an incompatibility between your version of Kino and
FFmpeg. It\ has been tricky to trying to manage this.
