Well, it can't find a database schema version number which it
writes at the end of any update including the initial update.
There should be about 40 tables but you only have 16. Without
a DBSchemaVer it thinks it should install a fresh database but
you already have about 1/3 of the stuff there. There's the rub.
Whether or not you remember (or would admit to it ;-) the process
died or was killed the first time you ran a myth process.
$ mysql -u mythtv -pmythtv mythconverg
mysql> drop database mythconverg;
mysql> create database mythconverg;
This will give you a clean, empty DB. Start mythtv-setup by itself
before running any other myth programs. Wait for it to finish
loading the database, uninterrupted, even if this takes a minute
