[mythtv-users] channel confusion

It looks as if things internal to the myth database are not the problem.
In the channel table each of the mixed up channels has a different xmltvid,
freqid, and mplexid. Each has the same sourceid (I have only 1).
In dtv_multiplex each mplexid has its own frequency.
Looking in the program table, the first overlap (same show at same time)
was 2021-02-27 06:00, although it doesn't seem to have become regular until
2021-02-28 18:30:00. So the recent lockup may have nothing to do with the
problem. The entries could have been mangled after they were created, but
my notes show I noticed problems with 65.3 listings on 02-28 just after I
created a rule. This was NOT while mythfilldatabase was running, which
does suggest a local problem.
I had a bunch of network problems in the week before that, and the
partition the database was on filled a month before that.
And I haven't made any attempt to verify what's in ~mythtv/.mythtv/cache,
which has lots of stuff for mythfilldatabase.
