[mythtv-users] Problems on an upgraded computer.

[Douglas Peale]

(Sorry, it seems I'm having trouble doing e-mail today and replied just to Mark Perkins, resending to the list)

I wiped out the old database and created a new clean one
    cd /usr/share/mythtv/sql
    sudo mysql -uroot -p < mc.sql

I set the password back to the old password
    sudo mysql -u root -pSE
    mysql> SET PASSWORD FOR 'mythtv'@'localhost' = "Old Password";

I restored the last working database from my old machine
    /usr/share/mythtv/mythconverg_restore.pl --verbose --drop_database --create_database --filename
mythconverg-1344-20180802130001.sql.gz

I changed the host name (Note that the command from the first link you sent did not work)
    /usr/share/mythtv/mythconverg_restore.pl --change_hostname --old_hostname="XXXX" --new_hostname="YYYY"

Everything looks the way it did on my old machine, but live TV still does not work. The following is an extract from the
mythbackend.log
