mythcommflag fails on corrupt data from recorded tv shows... (using HDhomerun) ... on abc (which happens to be a weak station approx 80 miles away) has sometimes bad data... but the canadian station (city-tv) is local and also broadcasts the show.. modern family. but isnt weak thus it doesn't fail...
when i checked the mythbackend status... the job queue, the abc recording errored , but the same show recorded on city-tv at the  same time... didn't error because it did not have errors in signal transmission. (for example signal drop outs etc)

the point is the i believe that the codec that decodes the channel
breaks/crashes/has-issues with corrupted signals... the abc signal is
720p... whereas the city-tv channel is 1080i... but that is not the
point. it is the mpeg2 stream that is "corrupted" breaks the
mythcommflag searching... so the fix would be to skip the bad data
fields.

not sure if this is the problem, but the mythcommflag "exit on error
140" correlates with a bad signal recording of HDTV recording.
