Hi Olli, thank You very much for your reply, it was misunderstanding on my side, because i thought that this module message: [ 102.005119] dvb_ca adapter 0: DVB CAM detected and initialised successfully means that CAM was initialized ... so i used : dvb-fe-tool -d DVBC/ANNEX_A -- my tuner was originally in DVB-T mode, so gnutv was unsuccessful ... gnutv -timeout 1 -out file /var/tmp/test.ts -channels ....... results are that i can tune channels correctly but i'm unable to watch encrypted channels, i used vlc, on wind* i can watch also encrypted :-( please could you help me ?
