Hi,

I have also added support for this card based on the little change you
showed here and some looking around in other drivers. I have gotten
information from technotrend that the proper i2c address for the tuner
is 0x61 (or 0xc2 as these adresses sometimes appear shifted for some
reason). With this address and the tuner driver loaded in debug mode I
seem to get some more response from the tuner, but still no lock. 

Now looking at the tda827x.c sources it seems this driver was
specifically written for dvb-t usage, and I'm uncertain wether it would
work out of the box for dvb-c. There are also some parts of the code I
don't understand, for instance the agcf callback. Harmut, do you know
anything more about this? The AGC2 gain value that is printed in debug
usually show 4 or 5 now, does this indicate a good signal or a bad
signal?

Also there is still the occational i2c timeouts that Stephen reported.
I'm not sure wether they are caused by the tuner or the demod, but they
appear to come so seldom that it should be able to complete a tuning
cycle. Any feedback on this would be welcome as well. Maybe Oliver has
some suggestions how to debug this?

Best regards

Sigmund Augdal
