Comment 2 for bug 453916

Problem fixed!

Adding package phonon-backend-xine removed the above error messages but lead to a new error:

demux_wavpack: (open_wv_file:127) open_wv_file: non-seekable inputs aren't supported yet.

Then I added
 - libxine1-plugins
 - libxine1-all-plugins

Now kaffeine is able to select and display the DVB channels!

I hope this will help.
