I checked out that link. My movies play just fine with both ffplay and
melt. Also, sometimes I manage to export a video, but most of the times
it fails. I also experience regular crashes of openshot while editing.

I googled on the errors I was getting, like the get_buffer() failed. On
http://ubuntuforums.org/archive/index.php/t-1349956.html, they discuss
the same problem but with another software. One thing mentioned is that
Nvidia drivers could play a role. I have an Nvidia card. Can this play a
role?

I'm currently at the point where openshot is too unstable to continue
using. Never had this in the past on older ubuntu versions. I hope
someone can help.

Title:
  Openshot crashes when exporting video

Status in OpenShot Video Editor:
  New

Bug description:
  I made a small movie (1'10"), but when I try to export the video
  (using profile BluRay/AVCHD), openshot crashes after approximately 80%
  of the process. I have installed the latest openshot (1.4.3) on my
  Xubuntu 12.04. I had the same problem with  openshot 1.4.0, which
  comes with Xubuntu 12.04 by default.

  Full dump of command line below:

  
  ------------------------- ERROR 1 ------------------------------
  Failed to import 'from openshot import main'
