[linux-dvb] AF9015 problems

[Lucio Crusca <lucio@sulweb.org>]

Hello *,

I'm new here, hope to be on the right list. 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:
