Thanks, cenwen,
It is not a pentium 3 is an intel Pentium D of 3.6GHz clock, EM64T capable  with 2 logicalcpu (maybe multitrhead). The other core2duo@2GHz clock.

That is not the problem, I do not know how, but from intent to intent 
I have installed ffmpeg with synaptic, and  ffplay plays avc/hd .mts videos.

OpenShot however is not working well in the fastest Intel D computer with an 
(it has an ati radeon xpress 200 host bridge 64bit 66MHz clock.)

The problem seems to be a version mismatch between FFmpeg and MLT, that
prevents to compile the last MLT (0.5.2) with the last FFmpeg svn
snapshot.

If I want to install with OpenShot Wizard that downloads everything from svn-git repositories, MLT does not compile (I also reported this problem to MLT),
I can not install MLT (0.5.2) the last in tar.gz (tarball) format. 
To see if it works fine wind AVC/HD H.264 MTS videos. The MLT 0.4.5 does not run smoothly those videos.

OpenShot 1.1 seems to call a MLT static-linked program, because it even works if ffmpeg is uninstalled.
The OpenShot 1.1 sample video was made in this format, so it must work in some platform. 

On the other computer, the one with core2duo (intel 945 chipset), 
I can not even run OpenShot 1.1, I also upgrade python 
but it is not copied to the usr ... dir, when executed this is the output:

$ openshot
--------------------------------
   OpenShot (version 1.1.0)
--------------------------------
A new frmMain has been created
No formats or codecs were found. Please check the OpenShot preferences and configure the 'melt' command name.
state saved
Segmentation fault

as described above.

There are other bug-reports describing the same problem.

On that computer 
$melt video.mts
just returns the help as if called without parameters.
On the computer where OpenShot runs, it plays the video, but not smoothly.
Both have the same version of MLT 0.4.5.
That hints that OpenShot may not work because MLT is not reporting something it verifies.

Status in OpenShot Video Editor: New

Bug description:
My camcorder produces an AVC/HD (H.264) HD 1080p and 1080i  (1920x1080 and 1440x1080) videos with an .MTS extension.
Those videos are not well handled by the ffmpeg 0.5.1 tar distribution in the ffmpeg site.
In order to see a smooth playback, one needs to download a snapshot of the svn or git repositories then:
./configure && make && make install.
Now ffplay video.mts  displays wonderful.
I installed OpenShot 1.1 in 2 computers, both with Ubuntu 8.10.
One can compile very well ffmpeg, I installed the OpenShot in tree different ways.
the .deb, the separate .deb and with the wizard.
In a Core2duo pc, where the ffmpeg works fine, I can't run OpenShot, a window is displayed very fast and I cant read the message, but executing openshot in the shell gives this output:

$ openshot
--------------------------------
   OpenShot (version 1.1.0)
--------------------------------
A new frmMain has been created
No formats or codecs were found.  Please check the OpenShot preferences and configure the 'melt' command name.

I think that the problem resides in the MLT version, which is:

$ melt -version
MLT melt 0.4.5
Copyright (C) 2002-2009 Ushodaya Enterprises Limited
<http://www.mltframework.org/>

maybe this version was not compiled with the last ffmpeg version, as the 0.5 seems.
I also tried to play the video with melt as explained in other bug report:
$ melt video.mts 
Failed to load "video.mts"
Usage: melt [options] [producer [name=value]* ]+

but, it does not play the video at all, just displays the options as if it were executed without parameters. On the other hand it seems to be well installed.

$ melt -query "producers"

In other computer, with an intel pentium maybe 3GHz, 32/64bit capable (I do not know exactly the model and configuration)
When I compile the ffmpeg svn or git snapshot, the ffplay is not generated. I copied the working ffplay to that computer and it performs good in full screen mode, but not very good (tilting) in the normal mode showing the window frame.    
I installed OpenShot, It works, I mean you can load the clips, but can not display the .mts video smoothly.
I tried to install it again with the wizard, but the ffplay was not generated.

Is there some thing that I can do, I failed to build MLT in both computers.
Or should I wait, that OpenShot 1.1 includes both last versions of FFmpeg and MLT?

Although I used openshoot in the second computer without watching the video while editing, I did an exercise using chroma key with a .png image and the .mts movie.  Adding the alpha channel to the .png because I could not see the .mts to select the chroma color. It was very easy, now I am more enthusiastic in using it. 
Thank's
