I tried this - result is here : http://pastebin.com/jh2by1aq but i'm
actually not sure how to interpret the entries..

I found out that the transport id, network id and service id are the
same used in kaffeine.

I'm not sure whether this can be done but as i also tried to set up a
completely new system as mentioned (mythbuntu 14.04.1) with a completely
new dvb-s channel scan, this doesn't seem to fix the problem.

Any ideas?
