Teletext on Digitenne is encrypted, and you are not the only one with problems. The teletext simply shouldn't be encrypted, but we can't control KPN. In some cases this can be solved by changing settings in the CAM menu. When saying the whole transport stream goes to the CAM, this means everything connected to the requested service ID gets decrypted (if the CAM is capable). So not just audio and video, but also extra audio tracks, teletext etc. To descramble multiple channels you usually need a more expensive CAM. For example http://www.made-in-china.com/china-products/productviewJqSxvLmUREWp/Professional-Irdeto-CI-Module.html shows a "professional Irdeto CAM" that will descramble 4 TV channels at the same time. Not usefull for you because you need Conax, but I don't know which Conax module could descamble multiple channels. This is no linux-DVB problem.

Linux-dvb missing in the reply-to field is very, very, very annoying. -- _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
