Hmm, that is true. dvb_defaults.h dvbstream/dvbtune/... has that correct
in FINLAND settings.

Even though the final responsibility of setting those values correctly
is the  application, since the driver also sets those (for defaults),
there should be good mechanism to flexible choose country/area/region
