[linux-dvb] Tuning doesn't work with Wideview driver

Hi, I have a card with the same ID, mine is  Freecom one. I do not use mine as 
it screws up my system (keyboard stops working, other USB peripherals stop 
working, kernel oopses,...), however, I had similar tuning problems. I found 
that editing the initial tuning data worked. I think I adjusted all values by 
167k, and that seemed to make it work fine, so try adding or subtracting that 
value from the values in the initial file 
/usr/share/doc/dvb-utils/examples/scan/dvb-t/es-Alfabia (make a new file), and 
see if that helps.

Good luck,

Benjie.
