I've just run scan with the frequency file for my transmitter [UK - SudburyB] and this seems to generate a file containing the expected set of channels which I save as ~/.tzap/channels.conf. I then can run tzap against each of the channels and it seems to pick up the PID from the channels.conf but doesn't give any data. Am I missing a step somewhere? example: mythtv szap # ./tzap five using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 690166670 Hz video pid 0x1781, audio pid 0x1782 status 01 | signal ffce | snr 0000 | ber 00000000 | unc 00000000 | status 1f | signal ffcc | snr b4b4 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal ffe7 | snr b6b6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK mythtv szap # grep ~/.tzap/channels.conf five five:690166670:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:6017:6018:12866 6017 decimal = 1781 hex which looks good, but is obviously missing something. -- Barry Myles
