The first time i saw it was that the DVB-S2 demod was returning no
carrier. After some time it was stating timing error for DVB-S as
well. Finally it all ended up with demodulator I2C ACK failure, and
eventually a frozen machine after a week (my test boxes run throughout)

Touching the demodulator, i happened to have almost a burned finger.
I wanted to know whether this was a single case. During the
development phase, i did mention it to Julian about this, since he
was the very first person to test for the stb0899 driver. He
jovially laughed about a burned demodulator and a finger, left his
machine on after i did some tests on it. Eventually he too had the
same results. Finally we changed cards.

I don't have such channels. Tested with a max of 27.5 MSPS
