DVBViewer Pro doesn't recognize my CI modules!

Recommended Posts


Hello All,


I just bought a DVBViewer Pro, and I want to use it to watch DVB-C TV.

It works for the free programs.

But I tried to use CI Module to watch non-free programs, it does not  work at all.
It seems that DVBViewer Pro doesn't recognize the CI module.

I also tried DVBDream and TBSViewer, both of them work for non-free programs.

So could you tell me what is the problem? Is it a issue of DVBViewer Pro or my  operation problem?

I have two CI modules, Irdeto and DVN. They have the same problem.

Is TbsCIapi.dll present in your installation folder (where DVBViewer.exe is)? If not, you did not install the TBS CI support. Download the latest DLL version from the TBS site and store it in the DVBViewer installation folder.


If TbsCIapi.dll is already present in your installation folder, your hardware has not been detected as TBS device. In this case please attach a support.zip. so we can see how it can be corrected manually.

I have installed the newest version of DVBViewer Pro 6.1.2.

So there is TbsCIapi.dll in the installation folder of DVBViewer Pro.

I also tried some things today:

1. Replace TbsCIAPI.dll with the file in TBSViewer, then I can watch the first non-free program when I Open the DVBViewer Pro. But when I change the channels, It still fails. And when I watch the program for a while, it crashed.

2. Replace TbsCIAPI.dll with the newest version I have downloads from TBS website tbs-cidll_v1.0.2.2.dll, I got the same result.

If I didn't replace the TbsCIAPI.dll, I can't watch any non-free program.

The attachment is the support.zip.

I know that TBSViewer is a TBS OEM media Player, which is bases on DVBViewer technology, so it is very strange  for me that DVBViewer Pro doesn't work while TBSViewer works.

Unfortunately the TBS CI implementation is known to be quite unstable. In some cases it crashes, in other cases it doesn't. Even slight differences may take effect on it. Here watching encrypted channels and switching to other encrypted channels works with my TBS USB Box and DVBViewer Pro 6.1.2. There are other issues under Windows 10 (sometimes the box is in an unusable state after hibernate), but that's not the point here.


Anyway... I will try to get the old OEM code and compare it with the current DVBViewer Pro Code. Maybe it reveales something..  I hope I will find some time for it next weekend.

I also made some try today, I tried to replace TBSCiAPI.dll with TBSCIAPI1.dll of TBSViewer folder, and it was also very unstable.


But when I tried to replace TBSCiAPI.dll with TBSCIAPI1.dll of TBSViewer folder, it is much stable now. Although it seems to be not fluent for a very little time after I watch encrypted channels for 35min. But now I have watched for more than 1 hours, and it still works now.


So it seems to be a TBSCIAPI.dll problems, I'm not sure whether it will bring other issues when I replace this file, because I have only one TBS USB device.


I think there should be some reasons , so that TBSViewer added 3 CIAPI DLLs (TBSCIAPI.dll TBSCIAPI1.dll TBSCIAPI2.dll).

      I'm experiencing strange difficulties with CAM decoding.
      My configuration:
      - 4 (2+2) Digital Devices sattelite tuners,
      - 4 (2+2) Digital Devices Octopus CIs with 4 CAMs installed.
      DVBViewer has:
      - 4 tuners disabled,
      - 2 rtsp (sat>ip) sources enabled.
      1. I choose Channel 1 > no decoding > enabling tuners and disabling rtsp > Channel 1 decoded > disabling tuners and enabling rtsp > Channel 1 decoded, Channel 2 not.
      2. I choose Channel 2 > no decoding > enabling tuners and disabling rtsp > Channel 2 decoded > disabling tuners and enabling rtsp > Channel 2 decoded, Channel 1 not.
      Earlier (before I reinstalled OS) everything was OK.

      Hallo zusammen,
      nachdem ich jahrelang sehr zufrieden mit dem DVBViewer mit einer TBS 6928 und HD+ war, habe ich hardwaremäßig auf Digital Devices (Auflistung s.u.) aufgerüstet.
      Die mitgelieferte Software DD TV, welche eine abgespeckte Version Ihres DVB Viewers ist, funktioniert die Entschlüsselung der HD+ Programme problemlos.

      Leider funktioniert die Entschlüsselung, beim DVBViewer, (weder direkt noch über Media Server) nicht.
      Freundlicherweise hat Herr Hackbart - vielen Dank für die schnelle Anwort auf meine Supportanfrage 🙂 - bereits mitgeteilt, dass " Generell kann man sagen, dass der Code für die Ansteuerung im DD TV der selbe ist wie im DVBViewer.  " und mich auf das Forum verwiesen.
      Eigenlich muss ich etwas falsch machen, finde aber keinen Fehler, weil die Devices in beiden Softwareversionen identisch hinterlegt sind. Oder gibt es noch eine versteckte Option für die Hardware?
      - Digital Devices MaxM4
      - Digital Devices Octopus CI Single PCIe
      Ich bin mit meinem Latein am Ende. Hat jemand eine Idee, wie ich weiter komme?
      Im Voraus bereit vielen Dank für Eure Bemühungen.

      Sehr geehrte Damen und Herren,
      ich habe vor kurzem eine TBS 6910 Dual S2 CI gekauft, leider bekomme ich die CI Module nicht zu laufen.
      - OS Windows 10 64bit
      - DVBViewer 6.x erkennt die CAMs nicht, CAM Menü ist disabled
      - Im Gerätemanager wird unter Ereignisse angezeigt das noch etwas installiert werden muss, allerdings habe ich den Driver von Ihnen installiert,, ich wüsste nicht was ich noch installieren sollte ……
      Im Attachment zugehöre Screenshots zur ausführlicheren Information.
      Mit der Bitte um Ihre Hilfe

      I've recently add recording service to have channels from computer on TV.
      FTA is ok, all is working fine.
      I have a DVB-S2 TT 3200 + CI + a DVB-T stick
      Question 1:
      When DVBViewer was stand alone, i had access to MMI interface. Since Recording service is intalled, option is grayed (no more access), why ?
      Question 2:
      When i select a scrambled channel on TV's DLNA ( and DVBViewer is not launched ), CI seems not to be used ,( i have check the box has ci module  in recording service configuration tool and reboot it some times) , Why ?
      Question 3:
      The only possiblity to have a unscrambled channel on TV's DLNA is to decrypt it with DVBViewer and then request the same channel on TV's DNLA.
      In this case, is possible to handle the funtionality of the CAM ( all CAMs on the market are now dual service) , watch a scrambled channel on PC and a other channel ( from same transponder of course) on TV's DLNA ?

      Good evening.
      Is it possible to use this card with CI but without any smart card in it? I wish to buy it because my Airstar is not PCIe and I have to change my PC. I use DVBViewer PRO. Thank you.
      Sorry for my poor English.
