I think I found the reason for this. In modules/access/dvb/access.c
lines: 146-149

        frontend_info.frequency_max =   12999000;
        frontend_info.frequency_min =    9750000;
        frontend_info.symbol_rate_max = 30000000;
        frontend_info.symbol_rate_min =  1000000;

Why are these values hardcoded? Especially given the fact that e.g. here
in Finland the terrestrial broadcasts come on frequencies between 538
and 714 MHz, which are way higher than the maximum values above?

I tried multiplying the frontend_info.frequency_max with 100 and
remaking the executable. That took care of the invalid frequency report,
but the tunig still fails, although with different statuc codes.

Where is the tuning code located? Is it in access.c or dvb.c (I haven't
had time to look them through properly yet), and where is the code
called from? I thought that I'd compare it with the dvbtune code and see
if that would help me..
