haven't tried yet, i didn't have a source at hand.
But looking at the linux driver (which is what i
was already doing) it seems that this board (and most of those
equipped with the tda10046 dvb decoder) needs to download
some firmware before tuner and decoder can be accessed.
This probably explains why scanning the I2C bus only detects the EEPROM
and nothing else.

ok - thanks for all the pointers. I will keep the list posted
if i make some progress.
