AF9015 problems

[Lucio Crusca <lucio@sulweb.org>]

Hello *,

I'm new here, hope to be on the right list (crossposting from  
linux-dvb@linuxtv.org which mailman told me is deprecated). 
I'm trying to tune a AF9015, but w_scan finds only 4 tv services, while the 
same dongle attached to the same antenna cable, on the same computer, with 
Windows Media Center finds as much as 135 tv services.

The 4 services it finds are all from the same 205500 KHz transponder. Any clue?

Some details:
