[linux-dvb] Re: Freecom DVB-T (new 14aa:022a/b model) not tuning

Are you sure that your /usr/share/dvb/dvb-t/uk-EmleyMoor is correct?

I'm in Spain and tried using the default es-Seville file but it didn't
work either. I think if the initial frequency isn't correct in the file
then nothing will tune (?).

In the end I ran the Windows application, did a scan of all the channels
and wrote down the frequencies, etc. I then updated the es-Seville in
Linux and it tuned OK.

Regards,

Stephen.
