Hi

how should I interpret the output of scan, trying to scan for HDTV in London?

initial scan file

T 554000000 8MHz 2/3 2/3  QAM64  8k 1/32 NONE

(I had found those values in this mailing list some months ago)

output:

Done.

Whet it says "WARNING: tuning failed" what does it mean?
Where does it get the frequency 522167000?
If it is given by the initial trasponder, why is it empty?
