One possible route to fixing your hostname problem would be to install
mythexport/mythimport and export all the new recordings.  You could
then restore from the old backup and change the hostname, then use
mythimport to restore the new recordings.  However, I have not yet
done a Python 3 version of mythimport.  It should not be too difficult
to do as I am in the process of converting all my Python 2 to Python
3, so let me know if you want to try this.
