I now installed totem-xine (2.16.2-0ubuntu1) and it appears it is also impossible to play SMB files with that backend for totem. After clicking on a file, Totem appears and all _seems_ to work well. It shows a message "Buffering 0%" in the status bar, but after a few seconds it changes into "Paused". I still figured everything was okay, but clicking "Play" made the "Buffering 0%" reappear and disappear again after a few seconds. Playing movies seems impossible.
