I found out that the card gets a lock in mythTV when the CI/CAM daughter card is not connected
(physically disconnected via unplugging the cable).

Trying to find out, where the problem is during the communication from mythTV and the CAM,
I recompiled libmythtv-0.21.so.0.21.0 and enabled the debugging in ./libmythtv/dvbdev/dvbci.cpp
via setting DebugProtocol = true;

I now get (still watching a non encrypted program):

Any Idea what causes the problem or any hint what other info I can provide ?
