Hi Jurgen, Ah, that's interesting. My T980C (and based on printout from Torbjörn his as well) have Si2168-A20 chips. Some things I'd like to understand: - is there a difference if the CI slot is populated or not? - is there any difference between the different firmwares? - does it work with the DVBSky provided driver? - when you say it doesn't work, is the issue that the demodulator does not lock on the DVB-T2 muxes? Two different firmwares for A30 chip: https://github.com/OpenELEC/dvb-firmware/blob/18b12de1f57b3c70a681983638989f94590b19f1/firmware/dvb-demod-si2168-a30-01.fw?raw=true https://github.com/OpenELEC/dvb-firmware/raw/dc7cf270e328de144e75a30d970b6e147e8bcb6e/firmware/dvb-demod-si2168-a30-01.fw I think the second one is newer, but don't have the means to verify right now...
