Someone ran a newer version of MythTV (mythtv-setup, mythfrontend, or 
mythbackend) than you're currently running against your current database...

Note, also, that 0.19-fixes is still using DBSchemaVer 1123, so someone 
ran SVN trunk against your database...

You'll need to upgrade to SVN trunk r8948 or higher to get to 
DBSchemaVer 1124.  Note, though, that the 1124 schema update is unlikely 
to cause problems unless you're trying to use DVB radio (this is not a 
guarantee of success, though, as downgrading is never supported).

Also, cardinput got a displayname in DBSchemaVer 1118.  However, the 
code is written to allow blank values (that's actually the default).  
The database should prevent NULL values.  So, I don't think the empty 
name is the problem.

Which is saying that although you have a videosource called Antenna, you 
forgot to associate it with inputs on a card.  So, go into mythtv-setup 
and fix your inputs...
