Sorry Klaus

For these mistakes ... I hope that this time the change to the source 
fits as it should be ...

In this way everything remains unchanged on other devices already 
operating ...

Add functionality to the card TechniSat SkyStar 2 DVB -S rev 2.3P

Tested by recompiling the sources VDR 2.0.3 ... Everything works ...
