Hope you had a nice weekend.

I tried ffmpeg (as root):
ds9 videoin # ffmpeg -vcodec copy -acodec copy -i 00109.MTS 00109_1.avi

As for mplayer/mencoder:
When I play the original file, there is no video (I stopped it at 2.3 s):

There were no errors, but the resulting file has bad artefacts.

You can get both files from my server
<http://aktuell.coolmule.de/00109.MTS> the original file from the camera
<http://aktuell.coolmule.de/00109.avi> the result of the last command.

I'd be glad if someone could take a look.
