why don't you use the hdhomerun config utility and see what the tuner
is actually doing when myth is tuning the channel. in case you have no
other computer, on android it is hdhomerun signal meter app. several
versions back i had similar issue and had to go into database and
correct the record but that was on clear qam. also try deleting the
channel and go into setup and do scan but limit the scan to scan
between channels 55 and 57 and see it finds the channel and then add
it.
