Hi Marcin,

that's true.

That's OK. It is not really a TDA9887, there's just something that behaves 
like a TDA9887 integrated in the TSBE5 tuner. So, if you've got such a tuner, 
you need the tda9887 module for TV (not for composite or S-Video).

That's not necessarily correct. To be sure, you have to open the card and look 
what crystal is connected to the SAA7134.

It would have been much coincidence if it did. That pulling GPIO18 low turns 
on power for the tuner is a very special thing in the Cinergy 400 TV mobile.

that's the tuner...

that's strange, maybe TDA9887 on yet another address ? Try adding this address 
at the beginning of tda9887.c

EEPROM found, OK.

Tuner found, OK.

Try it with composite input first. Try to find out the correct .amux/.vmux 
settings for the different inputs. If that works, try the tuner. You could 
try and set _all_ GPIOs high (hope it doesn't damage anything...).
Find good module parameters for tda9887. That'll keep you busy for a while...

Good luck,

Hans
