To my knowledge > no valid Nagra CAM do exist for DVB-C > I'm a bit fossil regarding current status of CA in DVB but anyway I can say I know that some years ago existed CI-CAM modules for Nagra, it was in time of so-called Nagra2 introduction on Hispasat ;) Dunno how is the current situation. An second - it has no difference if it is for sattelite or cable variant of DVB. The CI-CAM standard is the same. The only problem can be if support for particular provider is "baked" inside (meaning only particular auth data are inserted). /Honza -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
