Once you click on link, movie opens up and is downloadable, click on the movie and right-click “save as” and you can download it,  sometimes with the icon in the lower right in some browser players. If you have any problem with access, registration, etc., let me know via email gulagmagadan [at] tutanota.com
Email me if there are any problems as well and I’ll fix it and get the movie download working for you.
