I also installed the 8920 a couple of weeks ago.  I installed
the driver from the dvd that comes with the card.

The driver file from the web is named the same as the one on
the distribution DVD: v4l-dvb-0776e4801991.tar.gz

The driver works fine and the card scans properly with Kaffeine.  I
scanned Galaxy3C and Galaxy25 and I can tune all non-encrypted channels
on those satellites.

However 'scan' from both the latest version of dvb-apps and and
from version 1.1.1 won't find any channel.  I get "tuning failed".
I use a single Universal LNB.

I was surprised that you at least got a channel list from "A". So,
there might be a bug in the TBS driver.  But how is it that Kaffeine

My satelitte configuration is as follows: I've got a monoblock LNB, with
