Hi again
I found Kaffeine quite easy to set up.
To start when kaffeine starts up come a window with a menu, which if your tuner is seen by kaffeine should have 7 items on the menu, the main one is an icon that as this text
7 DVB Client This shows that the usb stick as been seen by kaffeine. If that icon doesn't show then you may have a problem, maybe you need the firmware for you device. Assuming your tuner is seen then at the top of the kaffeine window click on the item
DVB then on the drop down window that comes click on
Channels and it should start searching. If that is not successful you may need to click on
Configure DVB before starting your search. I found that the default setting for configure DVB usually works.
Hope this is of some use and you can understand it because it lost me.
