Thanks for it ;)

This seems not so good. But I am not the expert on it.

After months, I had last week some time to look again on the demod/tuner.
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'
