That's right. Is it worth switching from ffmpeg to the other one in the 
settings?

OK, but I have signal quality of >90%.

Hmm, I already lowered the level in the amplifier, because otherwise I 
would not get a lock on some frequencies. Maybe I have to go to an even 
lower level (not too low, otherwise I get problems with the analog signal).

Any ideas, what else I can do to get rid of those problems? Do I really 
need a TV technician who will spend hours measuring the signal 
throughout the house?

Thanks!
