The 2.x gr-atsc seems to be closer to working, at least the flow control
(forecast,consume,etc) creates the exact to-the-byte correct quantity of
output with no loss of sync (since it keys on easy to discern -5/+5), on
120MB size output files.
However the *quality* of the output is only about 65 percent correct,
which is not suprising if you compare the output of a working (0.9)
equalizer:

to a non-working all 2.x equalizer:

Any hints or wild guesses from the atsc experts on where to look? It
must be something with the bit_timing_loop or the equalizer but it is
largely just copied from the 0.9 stuff.
