I am applying THIS part to my tree.  I'll assume this means that you've 
tested both svideo AND composite.

What do you mean QAM is not working?  You mean it is untested, right?  
If VSB is working for you, then QAM will work too -- I have similar 
hardware (nxt2004, tuv1236d, saa7135) and have tested this myself.  
Chances are, the QAM testing may have been done using encrypted 
channels, which wouldnt work anyway.

There IS no driver for TUV1236D -- it is a simple, hybrid 
tuner,supported by tuners.ko (and dvb-pll).  The radio functionality is 
built-in.  Does it just not work?  Do you know for sure that the radio 
feature is available with this card?  Andrew Burri had included this 
with his original patch.... Andrew?

WHY do you remove this?  I am 100% sure that tda9887 is present inside 
the "tin can."  do:

"dmesg | grep tda988" while this is enabled and that will prove it to you.

Please include a Sign-off on all future patches.  This change that I'm 
about to apply is also present in your previous patch, so I will pull 
your S-O-B that way, but in the future, please include it explicitly.

Thanks,

Mike
