[linux-dvb] Incorrect tuning parameters for Perth Western Australia

The transmissions settings do change from time to time.  The only thing 
you can rely on is the frequency, and then it could change as well, but 
only +-125kHz.  I have found with my Dvico Fusion Plus card that using 
auto for everything works, and the card auto detects the 125kHz offset 
as well. I don't know if all cards support auto but I am pretty sure any 
reasonably new card would.  I also think that is must be a requirement 
for Australian cards because the only setup parameter which may be 
required is what state you are in, and even then you can work that out 
from any TS data which is found.

I know that many DVB apps require the channels.conf file but I think 
it's format causes lots of problems.  Here in Melbourne, lots of 
channels change frequently (Channel 7 changes things almost weekly).
