''Remark about the video recordings:'' we have prepared videos in different formats, in particular: ''.m4v'', ''.mp4'', and ''.wmv''. If you click on one of the links "Video recording" you get that format of which our script thinks that it best fits your device / operating system / browser. If you explicitly want a particular format, simply copy the link address and add the desired extension by hand.
