Hi, I am just looking into the CA implementation of linuxtv. I allready did a well-working DVB-S-viewer with the linuxtv API. Now I'd like to add CA-support to it. Looking at the docs (http://linuxtv.org/docs/dvbapi/DVB_CA_Device.html) The structure of the CA device is almost clear to me, but I can't find any information about what has to be send to the CA to actually make it decrypting something. Is there some more information I missed out? - Or maybe some sample-code? Cheers, Julian
