Hi Oliver, I'm not sure if you missed my last statement, that the patch works now fine in my environment. But I use the changed value not only for QAM256 but for every Modulationrate. In that case I can get rid of the unofficial frequencyshifting in av7110.c, where I had to tune down every

Hi Oliver, Hartmut I have to modify my last statement concerning this patch. I forgot that I had to use a frequency shift in av7110.c to achieve a good reception. If I set this shift to 0 and use the new value of initial_demod_freq I get a lock again on QAM256-channels with reception as good as
