Thank you Kushal, The problem was indeed created by a conflit with the deb-multimedia repository. I fixed it by stopping using this repository and downgrading all the packages concerned. It seems there is less reason to use deb-multimedia these days. The official (unstable) repositories contain almost the same version of packages. The only program I didn't find is avidemux. Pétùr
