Sorry, I think you misunderstood - the point is to check your *source*
files with ffplay/melt. As the ffmpeg libraries & MLT provide the format
& seeking support for OpenShot, we need to identify if they can handle
the files properly first (the seeking is important as you are trimming
your file, rather than just simply playing it back). If they have a
problem with your source files, then OpenShot will too.

The latest MLT is available in a PPA, ppa:sunab/kdenlive-release. This
will only work with OpenShot 1.4.3 & above.

Title:
  previewing effect of video edits causes Openshot + Desktop to freeze

Status in OpenShot Video Editor:
  Incomplete

Bug description:
  Openshot 1.4.3 installed via PPA under Ubuntu 11.10 as per guide on
  Openshot website.

  Initial messages on start-up:

  charlie@fiona-ubuLenovo-3000-G530:~$ openshot ./Pictures/100CASIO/CIMG1113.AVI &[1] 5498
  charlie@fiona-ubuLenovo-3000-G530:~$ 
  ------------------------- ERROR 1 ------------------------------
  Failed to import 'from openshot import main'
  Error Message: cannot import name main

     OpenShot (version 1.4.3)

  Process no longer exists: 5295.  Creating new pid lock file.
  Adding files to the watch queue:
  /home/charlie/Pictures/100CASIO/CIMG1113.AVI

  Detecting formats, codecs, and filters...

  etc... 

  application seems to load / run.

  Use the Resize tool to shorten the AVI file loaded above (size is
  approx 13MBytes, generated by a Casio ZX-60 camera); resizing is
  successful and modified AVI file can be saved as mp4, replayed with eg
  Movie.

  BUT: if I use the 'preview' button to check result of the re-size
  before  saving/exporting the video file, the Openshot GUI locks up.

  Moving mouse to left of screen to 'activate' 'Dash' launcher has no
  effect; Alt-Tab has no effect (there are other apps running).

  Ctrl-Alt-F2 DOES bring up a console where root can login;
  Python/Openshot are NOT taking an excessive amount of CPU (virtually
  none..).

  kill -9 'pid of Openshot' restores normal system function.
