Hello martin,
thanks for your patience.
Okay .. but you still can reduce your system down to one DVB-S card ..
Yes, that I will do.
So, what do you plan to prove that your multiswitch is not broken?
I've changed it to another one.
What do you do to doublecheck, that your sat dish is correctly set up?
Ups, this sounds like I angered you. Sorry, if I did.
If the dish is misaligned, I assume I would have problems in all channels, wouldn't I?
Off upstairs to remove all but one card, and see what happens.
