Description of your issue, suggested solution and other information

New versions of Presentations2Go (like above) cannot be downloaded, as they give an HTTP 403 from the generic downloader. Looks like the video streams are implemented in DASH. Older versions work fine (e.g. http://wurtv.wur.nl/p2gplayer/Player.aspx?id=es1dnH ).

One thing that makes Presentations2Go a bit unusual is that it is two video streams (camera and screen) playing simultaneously.
