The initial tuning information is get on websites like lyngsat and kingofsat. This information can also found on the channel providers websites, on the satellite manufacturer website etc ... In the case of the DVB apps, you will see from time to time people which proposes patches on the mailing list to update this information (especially for terrestrial) For your information scan doesn't need to know about all the transponders since (normally) in each transponder there is packets to announce the other transponders of the same satellite For scanning without initial tuning files this is possible in terrestrial with w_scan (which basically tries all the possible frequencies) I don't know any software which do the same for satellite, I think it's mainly because the number of possible frequencies is too big I hope this will help you Best regards -- Brice -- 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
