If I run a scan as follows: ./scan dvb-t/uk-CrystalPalace I get a list of _write_dst errors in dmesg and get "tuning failed" during the scan. The results of the scan are as follows: ====== scanning dvb-t/uk-CrystalPalace using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 505833333 0 3 0 1 0 0 0 >>> tune to: 505833333:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_NONE:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE WARNING: >>> tuning failed!!! >>> tune to: 505833333:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_NONE:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE (tuning failed) WARNING: >>> tuning failed!!!
