The ZL10313 demod is just a newer MT312, which is fully supported ;) The tuner isn't so easy ... I think the i2c address behind the demodulators secondary 2 wire bus is 0x60... but the datasheet says, it should be 0xc0 / 0xc1 ?! A first simple patch is located here: http://www.mcmilk.de/projects/dvb-card/patches/ ... maybe someone can look/help at the implementation of the zl10036_set_params() function. There are also these three logfiles: 1. after initialization 2. after tuning 3. output of 'scan dvb-s/Astra-19.2E' -- regards, TR
