That's true, I don't know, why upc is using QAM256 (bandwidth problem?).
I heard, that other users also have severe problems.

When I use the plugin signal-information I get the following output.
Could anyone plase explain me in short word, what this means?
Maybe I could change some things.

ORF2 (is working just fine)
STR      100%               BER 00080a98          Video 5,91
SNR  eded 92%               UNC 00000001          Audio 183 

ATV (I get the last picture from the last channels, sound is "krächzend")
STR  ffff 100%              BER 009514ba          Video 1,71
SNR  e6e7  90%              UNC ffffffff          Audio 64 

VOX (no picture no sound)
STR  ffff 100%              BER 00083c70          Video 3,79
SNR  ecec  92%              UNC 00000000          Audio 0

On all the channels, I get also
LOCK SIGNAL CARRIER VITERBI SYNC
in yellow letters

Thanks for any help
Gerhard
