Hi Michal, I've seen something like this before with some CAMs. It seems that the CAM needs to be initialized if it is plugged in. This does not happen if you use software which does not have CAM support (such as w_scan). The linuxtv.org wiki has the following comment on the CT2-4650 page: Some CAMs require initialization before they will work. Without initialization it's possible that even non-encrypted channels do not work. If there's no CAM inserted, there's no issue. gnutv could be used to initialize the CAM, for example: gnutv -timeout 1 -out file /var/tmp/test.ts -channels ~/channels.conf FOX Of course ideally the CAM should be initialized by the driver...
