The 2.x version of atsc_field_sync_demux has been proven to work.
The equalizer still looks like an issue with symbol/tag alignment -
A working 0.9 system demux syncs on a (FIELD-2) at 3277436, while a
failing 2.x system syncs at 3277487 - a difference of exactly
d_offset = ntaps - npretaps - 1 (51).
How to do the 0.9 alignment scheme:
inputs.index = output.index + offset; // align equalizer tags
in gr 2.x I have NO idea.
