A video source is a list of tuning information for a bunch of channels. 
Therefore, if two tuners can tune the same channels, then you don't need to scan 
twice, just attach them to the same source.

You might make your configuration a little less error-prone if you called your 
sources "Astra1", "Astra2" and "Hotbird". They are only identification strings, 
after all, and giving them relevant names will help avoid mistakes in the 
future, when you have forgotten what you originally did.
