What instructions?  Are you referring to the GRANT line?  I did that
yesterday.  As for the mythbackend server IP, I set that two or three
days ago.  It's in the database correctly:

mysql> select * from settings WHERE value = 'BackendServerIP';
+-----------------+-------------+----------+
| value           | data        | hostname |
+-----------------+-------------+----------+
| BackendServerIP | 192.168.1.3 | camille  |
+-----------------+-------------+----------+
1 row in set (0.00 sec)

What else do I need to do?
