Hi, If I enable update transponders setting one (C-mux) of the available three (A,B,C) multiplexes gets updated to non-working frequency. Example: "The Voice;SBS:770000:I0C23M64B8T8G8Y0:T:27500:513:660=fin:0:0:241:8438:12289:0" becomes "The Voice;SBS:674000000:I0C23D23M64B8T8G8Y0:T:27500:513:660=fin:0:0:241:8438:12289:0" The same happens for other TV and radio channels in the same frequency. It is funny that the in addition to wrong frequency there are also three extra zeros in the updated frequency. I contacted the Finnish operator (Digita) and was lucky to get in contact with a helpful person. He verified that other NIT data is sent correctly here in Tampere so I wonder now if the problem is in vdr. He also told that the NIT data is sent in two parts, first A and B and then C separately. Could it cause that A and B work but not C. The log of vdr shows no further interesting information about the problem. BR, Seppo
