Debug looks OK. If you have another board where you know for certain 
that tuning a specific 8VSB frequency works, then tuning this same 
frequency with the LG should probably work reliably.

In terms of the tuner-to-demod, are you confident that the I/F is set 
correctly? (And inversion for that matter?)
