Help! 

Mythtv can see my four Duoflex adaptors but can't see any channels.

scan gives output like -

>>> tune to: 
682000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_64:TRANSM
ISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE
>>> tuning status == 0x00
>>> tuning status == 0x1f
WARNING: filter timeout pid 0x0011
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x0010

And says no channels.

w_scan says -

Info: no data from NIT(actual)

And again no channels.

dvb-few-tool shows all adaptors set to DVBT.

So, it looks like we're turning but perhaps the demodulator isn't being 
programmed correctly, or something?

Maybe I need to take this to the linuxtv site instead of mythtv?
