Picasa not analysing one directory

I have Picasa version 3.9.139 on Windows 7
It is suppose to permanently analyse directory f:\photos and f:\videos (one big external disk).
Indeed it does it correctly, except now f:\videos\2015 where I put several video recently.
When I look in tools to directory analyser (french : gestionnaire de dossiers), I see that the 2015 subdirectory is indeed marked to be always analyzed but in Picasa, nothing is shown

ps : the videos that are not detected are from my Panasonic camera, files *.MTS ...
It could that Picasa does not understand the format in which videos are created.
If so, you have to either install a plugin to Picasa with the required codec or upgrade maybe, or just convert videos to another more common codec before copying them to that folder.
