It's not like I did not look at this datasheet 2 years ago.
But it does not help if you don't know if and where those 
pins are connected. And the cards do come with different versions
of the chips. I have seen them with LNBP 11SP and 16SP.

The WinTV Nova with LNBP 16SP I am holding in my hands right 
now does seem to have a connection at pin 10 but it is pulled down
to ground with a resistor. Two other soldering points, one of which
is also connected to pin 10, next to this are not connected by a
resistor. Even it were connected I would have to know where it leads.
