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. > > Does your mantis driver work ok with such channels? I don't have such channels. Tested with a max of 27.5 MSPS Regards, Manu
