it then starts to use VCO2 instead of VCO1.
I have now (hack, hack) changed the segment start from 390 to 395MHz
so that the 388MHz is still tuned with VCO1, and this works OK!!
TechnoTrend C-1501 DVB-C card does not lock on 388MHz.
I assume that existing frequency table is valid for DVB-T. This is suggested
by the name of the table: tda827xa_dvbt.
Added a table for DVB-C with the name tda827xa_dvbc.
Added runtime selection of the DVB-C table when the tuner is type FE_QAM.
This should leave the behaviour of this driver with with DVB_T tuners
unchanged.
This modification is in file tda827x.c
I imagine if there´s something similar to my card, as it doesnt seem
to use the same tuner. dmesg only says this:
