Comment (by tilman.wagner@…):

 The problem I am seeing may be specific to my installation, because it has
 components from 3 different manufacturers:

 Using the very same physical hardware I installed tvheadend on mythbuntu
 to see if that can correctly address the Spaun SUS 21 F unicable
 multiswitch. I did not work either, however it does do something
 different: While with MythTV the switch indicates "orange" (=remote supply
 voltage > 15 V) with tvheadend it indicates "green" (=remote supply
 voltage > 15 V) and sometimes "flashing green" (=valid DiSEqC command). In
 either case it does not find any transponders or channels though.

 So the error could be basically anywhere in the communication between the
 Kathrein LNBs, the Spaun multiswitch, the Spaun unicable switch, or the
 Technisat Skystar USB HDs DVB-S2 cards. And maybe the MythTV unicable
 setup cannot be saved just because MythTV checks if the source is valid.

 Therefore I am returning the Spaun Unicable components and will now try a
 different unicable solution with a Onecable Stacker/Destacker in the
 DiSEqC enabled version (Manufacturer: Global Invacom). These two boxes
 completely encapsulate the Unicable path and I should be able to just use
 standard MythTV without the Unicable patch at the two outputs I will get
 in my appartment.
