Tvheadend

I have the following setup:

- Ubuntu 16.04LTS - fully updated
- Digital Devices Cine-S2 (V6.5) + DuoFluo CI
- TVH version 4.1.2154

I've followed the instructions to install the drivers as per http://support.digital-devices.eu/knowledgebase.php?article=152

The FTA channels work perfectly ok:

But scrambled channels don't show and no error is generated. The CAM's and CI's have been tested with other (hardware) receivers and has worked on a setup with MythTV on the same PC before (including scrambling).

Why can't I see scrambled streams? I have no clue why they don't unscramble. In a reply in the "recommended hardware" posts I see Paul Farquhar confirming that the DD equipment should work.

Any tips what I may be doing wrong here? any idea's how I can get the scrambled streams to work?
