Good idea.

HowTo? I don't think there is one. There a discussion about the 
Xceive-tuner as a dvb_frontend some time ago. Markus did something I'm 
sure.

There are 5 GPIO free on the USB-device and 4 or 5 on the demod, one of 
them it is.

The 843 mentioned in the .inf-file is the Conexant 25843. The comment 
about NO AV and so is confusing and maybe misleading: this seems to be a 
design based on the STK7700PH ref design from DiBcom. (single hybrid).

Maybe with some quirks.

Once the Xceive is working you will need some special setting for the 
demodulator (Xceive is using a IF frequency of 5.2 MHz and has only an 
internal RF gain control). I will provide them when needed.

Patrick.
