I have 2 iMacs. On both Jaksta is not downloading videos from the link you provided.
One is a 2009 iMac running 10.11.6 and the other is a 2013 iMac running 10.12.2.
The settings "Always Record HTTP" and "Always Record RTMP" make no difference.
On both I have Jaksta version 1.3.3. (139) installed.
From other websites Jaksta is still downloading as usual.
