Thank's Andy,

I installed melt, I can play the .MTS file with melt 00001.MTS, it looks
fine, but send some reports that I pasted at the end of this message.

When I run openshot does not work, here is the message from openshot, followed by the test to load mlt 
which failed.

What should I do, I tried to reinstall python, which is the latest
version, there are many python modules that may be installed, which
should I install or what should I do with melt to work with Openshot?


 $ openshot

OpenShot has failed to import some of the Python files or libraries 
required for our application to run.  Here are some trouble shooting
tips:

Tip 1) Check if MLT can be successfully imported in Python.  Run the 
 following commands, and see if any errors are displayed.  If you get 
 an error, you need to investigate the correct way to install MLT.
 NOTE:  Do not type the $ or >> characters in the examples below.

       $ python
       >> import mlt
       >> mlt.Factory().init()

Tip 2) If MLT is working from the first example, then the next tip is 
 to look at the above error messages very closely, and google for more 
 help.  It's likely the problem is already reported, and maybe there is
 a simple work-around.  Also, you can search for bugs or report a new 
 bug at https://bugs.launchpad.net/openshot.  Good luck!

I did the test here is the output:

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
  Linux computer 3.0.0-24-generic #40~lucid1-Ubuntu SMP Wed Jul 25 14:03:01 UTC 2012 x86_64 GNU/Linux

  Here is the output, when launched from bash.

  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.
