I just saw this after I posted my reply. Very interesting, as this
sounds like it may in fact be the same thing I've experienced with NBC
out of NYC after they moved. To clarify one thing: I only use the
command line hdhomerun_config. When everyone refers to "symbol
quality" is that the same as the "seq" (signal error quality as I've
always understood) in the command line version?:

ch=8vsb:605000000 lock=8vsb ss=85 snq=82 seq=100 bps=8390816 pps=797

If so then what I've seen is in fact that same issue...where that
drops to 0 on occasion.
