Thanks,

     This is my current situation:

- I've upgraded to xbuntu 19.04, which includes MythTV Version : 
v30.0-v30.0-13-g1c2068c62b; but that didn't help.
- I've compiled and tested using tvheadend which made me realize that my 
CA module was inserted wrong side up. But while, like with Mythtv, I'm 
able to watch TV Sat channels which are being sent in the clear, I'm 
still unable to decrypt the Swiss channels.

- My latest test with Mythtv show that the adapter 
(adapter2/frontend[01]) with the CA card inserted doesn't work with 
Mythtv, while the first adapter without the card does work with 
mythbackend; well more or less, the results are not 100% reliable 
(tested on V30.0-13). On the adapter which does work, the decrypting 
doesn't work, which isn't surprising given that the CA card is inserted 
in the other adapter.

  Now, I have tried using source (master) with the DVB from the 
tbsdriver; for reference:

    ./configure
    --dvb-path='/soft/sources/Unix/tbsdriver/media/include/uapi
    -I/soft/sources/Unix/tbsdriver/media/include' --with-bindings='perl,
    python, php' --enable-libmp3lame --prefix=/usr/local/

root%mytv[32] /usr/local/bin/mythbackend --version
Please attach all output as a file in bug reports.
MythTV Version : v31-Pre-517-gc3e7f806d0

using_mythtranscode using_opengl using_vaapi using_vaapi2 using_nvdec

     So any suggestions on what my next steps should be to debug this 
situation?
