No, therefore the warning that I did not look any closer yet. http://www.tclrf.com/English/html/enewsproopen.asp?proname=102&url=product > "struct tuner_params tuner_tcl_2002n_params[]" in > v4l-dvb/linux/drivers/media/common/tuners/tuner-types.c > doesn't have ".has_tda9887 = 1" set. I assumed a MK4 tuner=57 on it like it is also on PVR-150 and PVR-500. They also have no radio, but without tda9887, includes tda9885 and tda9886, you won't get anything useful out of them. Then exactly the above missing .has_tda9887 = 1 for _that one_ could cause such problems. > > Thanks. > > If you have any other thoughts/idea, please let me know. It just came in mind it might be related to the missing tda9887 for tuner=57, but you obviously deal with other tuners. However, the missing tda9887 for the FQ1236A seems to be at least a inconsistency in tuner-types.c for me. >From logs of the PVR-500 and PVR-150 one can see they need the tda9887 module and it is at 0x43/0x86.
