Hello

I'm stucked here with a problem with a new Hauppauge card called Nova 
TD-500.
When tuning, I got lock on 4 of 5 muxes.  The fifth, non working mux, is 
at 778 MHz.
It's same behaviour on both tuners, with tzap or MythTV,  with or 
without lna option.
I have also tried with another computer with same result.
The signal is not a problem. I have 3 other dvb-t cards up and running 
for the moment...
All muxes are from 538 MHz to 778 MHz (64 QAM, 8 MHz bandwith, 8k 
transmission mode)

Some more information/dump ...
