Please, enable cwc and descrambler trace (--trace cwc,descrambler).

Could you show me the service info dialog for the "V3 STOCKHOLM" ?

TV3 STOCKHOLM ...

I meant the info in the dialog which appears when you click on the "i" icon on left in the service row..

It looks all ok. The descrambling works without any error messages and I don't see anything suspicious. Could you try to set the "pass-through" in the default DVR config and try another player (vlc, mplayer) directly (just copy the link for a service or channel from the "Play" column)...

Something happens at least with pass-through:

But can't play it.

Freeview channels work though (but kind of laggy).

I am on OSCAM r9847 together with TVH 3.9.1447 and Ubuntu 14.04. I watch Canal Digital Nordic channels also but via the Telenor THOR 0.8W satellite.

I had similar problems until I turned off "Network Discovery" and "Idle Scan Muxes" in TVH.

Was your scrambled channels working ok before or has it always been a problem?

Turning of "Network Discovery" and "Idle Scan Muxes" does not do any difference for me.

I tried commmit 4bce3dc4aeda9b5c6338c09bcd07d35accc94983 today. Still same problem.

Is there anything else I can help out with?

Do you have any other device using oscam ? Does it work ? It looks like that the keys from oscam are invalid..

Could you gather logs from oscam for ProgDVB and tvheadend for one channel to compare?

Could you try this change in the code?

OK, another idea - could you try to use the 'capmt' client rather than cccam ? The oscam handles more key logic itself in this case, and perhaps, something special is required for you CAS.

Also, don't forget to include the descramber to the trace, like 'descrambler,capmt,cwc' ..

I assume that it does not work. I'm getting out of ideas. Everything seems good, but used keys are not valid (thus the descrambled packets are not valid). Note that other 0500 CAID cards works without any issues.

Probably ProgDVB does something with keys before they are used..

Looking to oscam sources, the even / odd keys might be swapped..

Could you use your card with any other open source program (to check sources) ?

Are there any suggestions for other open source programs? The only one I have used is TVHeadend.

I have set up MumuDVB, but for some reason scrambled channels work even without me having configuring the oscam part. I think they are showing all channels for free today.
