Hi

there's one sat-provider from 9e which is sending NIT with wrong parameters 

            Frequency: 18437984 (=  11.95760 GHz)
            Kind: 0 (0x00)  [= DVB-S]
            fixed ('00'): 0 (0x00)
            Modulation_type: 2 (0x02)  [= 8PSK]
            Symbol_rate: 2506752 (=  26.4000)
            FEC_inner: 2 (0x02)  [= 2/3 conv. code rate]


how VDR will manage with that table and with option "add new channels and transponders" ?
