As you have mentioned yourself, the problem is with your version of MLT.
The latest versions of MLT play HD files quite smoothly. To get the
latest version (0.8.2), use the following PPA:

https://launchpad.net/~sunab/+archive/kdenlive-release

The same PPA also has the latest version of the frei0r effects library
which you may also want to update. Decativate the PPA after you have
updated MLT.

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.
