Yeah... hope everythings also fine for you! (guess it could be better :-)

If you meant as a "hint" the word DVB_T, then it still does not help me very 
much... why should there be a serial clock _input_ be specified? 

Is this Macro defined, when TT builds the firmware? AFAIK (haven't tested this 
yet) this card should run with the standard drivers in Win...

If I get this right, this could mean the following:

My assumption that the SP5668 is controlled by the av7110 is wrong.

There are other possibilies in the AV7110 to drive the three lines to the 
SP5668. 

  Johannes> What now?

dunno... wait for response from TT :-) 

I think I will plug the board these days in a Win Box and look what is 
happening...

Thx for your first ideas!
