The original problem was not to set all parameters to wrong values (this 
is what you are doing NONE is wrong in this field, AUTO, 1/2, 2/3, 3/4 5/6 
and 7/8 are valid) and then let the demod guess what might be correct, but 
to see if parameters set to AUTO are then really autosearched.

"Good enough" is not the correct term. This is not a tuneable parameter 
but a fixed one telling you which FEC is used by the boardcaster.
