Thanks Andy,
this last issue is solved!

I found the solution in this bug report:

https://bugs.launchpad.net/openshot/+bug/1036097

For those who have the same problem, be aware that python-mlt is not
automatically upgraded.

When python failed to load melt, I marked to complete remove in synaptic
package manager, then I installed again, but that did not remove the
python-mlt, that I found searching mlt in the installed section, where I
saw it was a 0.5.x version, so I removed it manually, and installed the
last version 0.8.2 at this time.

Title:
   .MTS video does not play in Openshot 1.4.3, some errors reported
  after running in shell

Status in OpenShot Video Editor:
  Invalid

Bug description:
  I like Openshot, I think it has a great design, thanks to Jonathan. But I have never been able to use it, because I have an AVC/HD camera, a complicated video format, even for the proprietary windows software included with the camera.
  In previous versions I could play inefficiently .MTS files, but in the present version 1.4.3 the screen shows white, and the soun stops every second. (I includded a screenshot attachment).
  The program crashes frequently.  Recently I reinstalled Openshot in this computer:

  $ uname -a

  Here is the version of melt

  $ melt --version
  MLT melt 0.5.4

  Openshot was installed copying the ppa lines in openshot page, to bash, then sudo apt-get install openshot
  As far as I know, I did not installed melt alone, It maybe was installed as a dependency when Openshot was installed.

  It seems that the problem is the melt version, because I can't neither
  play .MTS videos with  $ melt file.MTS

  Unfortunately Ubuntu freezes the last version of each application in
  each distribution. It could be the source of the problem, because apt-
  get does not install the newest melt version.

  It seems that Jonathan owns a Canon HD camera which records the same
  video format that has been shown problematic with Openshot and other
  applications in my system.

  I hope this helps to improve Openshot.
