I extracted firmware to an extra file. I disassembled parts of the windows driver to verify some assumptions. So the calculations should be almost correct for dvb-t. But for dvb-c I need some more knowledge or more disassembling to know how to calculate some register values. e.g. What is the equivalence to this dvb-t value: DVB_rate = BW * 8/7 I guess it should depend on the symbol rate of the dvb-c channel. I hope I manage to send out the current state as patches the next days. Regards Matthias
