Well you are right, I guess seeing is believing.

I had to try harder to get it to show up. But finally I see it now.

Here is what I had to do.

   1. load saaa7134
   2. load saa7134-dvb
   3. run something to get the nxt2004 firmware to load, like azap.
   4. load tuner
   5. remove tuner
   6. load tuner (it always loads the second time)
   7. remove the tda9887 that was loaded by someone else.
   8. load tda9887 (now that the ntx2004 is up).

The result is that it loads and tries to do it's thing. I don't notice 
any difference in the TV signal but with the debugging enabled it is do 
what it does. Is it possible that the nxt2004 was already controlling 
the tda9887 on it's own?

I will play with this more tomorrow.

Curt
