Progdvb is not doing a good job at Channels lists and their management. The best is to begin from scratch. First clear the channel list. Edit the transponders file manually using notepad, and make a fresh scanning of the satellite. You will have all the available channels. Also, after the sanning is finishined, if you want to scan more transponders, just manually scan them. This transponder will be added to the channels list, but will not update the transponders list permanently.
