Thanks for that. I suspect that something like that is what is wrong.
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?
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 |
status 1f | signal ffe7 | snr b6b6 | ber 00000000 | unc 00000000 |
mythtv szap # grep ~/.tzap/channels.conf five
6017 decimal = 1781 hex
which looks good, but is obviously missing something.
