I have a Nokia Dbox2 with command 8 but last week foresome reason all the channell have disapeard. I have rescaned but this only wiped out the channell list leaving a number of channels 'which can't decode'. The box denotes 'No EPG info' as if a transponder not working or if l'm using a wrong frequency. As you can see i am not very knowlegable about this process. any suggestions?
