This is only required by Kaffeine. The idea is to use the cam only for 
scrambled channels (and as you have noticed the "scrambled" flag isn't 
reliable), so if you are recording a scrambled channel and want to live play 
a second FTA channel on the same mplex, you can.
Most apps (like windows ones) simply use the cam for any channel. This may 
have some advantage, but also some limitations.
