Looks like fixed by linux 2.6.33 just in time, BIG Thank You guys ;-)

Even at higher BER:

I'll report if issue reoccurs and try to finetune crystal based tuner/demod parameters, then.

Hi,
Issue is already confirmed here:

Linux 2.6.32.8, 80cm dish.

Do we have any Tuner/Decoder optimization points in the FE code?

This is not OK:

Low signal strength values are AGC-loop misinterpretation as usual?
