I am now pretty much convinced that the problem is in the database, or
in the connection between mythtv-setup and the database. In addition to
the weirdness described earlier (cannot delete capture cards through
setup, have to do it through mysql; HDhomerun tuners added through setup
showing up twice in mysql; etc.), I now see that if I go into video
sources and look at the Antenna source, the ComcastDigital lineup is
shown. I can apparently change it to the correct one, but if I go back
in there again, it is wrong again. This is no doubt related to the
tuning problems. But if I look in the videosources table, the lineupname
field is correct! WTF??

In the hdhomerun_config_gui, there are channels in there that can be
tuned with Signal Strength, Signal Quality, and Symbol Quality all at
100%, but they cannot be tuned from LiveTV in Myth. I still see the
"TI__) No Lock".
I cannot easily install vlc on this machine. It is an old Fedora 10 box
that I had to install a bunch of stuff by hand to make Myth work, and
the only place I can find vlc is in rpmfusion and it wants to pull in a
bunch of other stuff like ffmpeg and faad2 libraries that will likely
conflict with what Myth is using. I don't want to risk it. So although I
cannot use the View button in the gui, I still think that at this point
I can rule out antenna tuning and signal strength issues. It is clearly
a configuration (i.e. database) problem. The fact that mythtv-setup
doesn't modify the database tables correctly is very worrisome. I am
thinking of starting over with a brand new empty database, but I don't
want to lose all my recordings. Maybe I can find something on the Wiki
that would tell me how to save this data? Which tables I would need to
dump?
And yes, I did double and triple check that every mysql.txt and
config.xml file that I could find had the same settings for
LocalHostName and DBHostName.
