For the benefit of the OP, can we go a step farther and say that Myth
requires that any channels with different programming content must have
unique callsigns? The OP does not have his system set up that way
("I've been unable to browse listings for channels with duplicate
callsigns, even though they have different programming.").
The reason I'm asking first is because of [13407] (
http://svn.mythtv.org/trac/changeset/13407 ). Regarding that change,
Daniel, are we really saying that blank callsigns are allowed in a valid
MythTV configuration or is the extra code just to try to prevent
failures even with broken configurations? After all, channel.callsign
is a NOT NULL column, so officially allowing the empty string sounds
like extra work with no real benefit. (Not to say trying to recover
even with broken configs is bad, but I just want to ensure I don't pass
on bad info when I tell people we need unique callsigns for channels
with different content.)
Thanks,
Mike
