A couple things I would like to suggest (I am the MyMote developer):

1. The fact that the key bindings retrieval isn't working is a  
separate issue from anything else. This shows that using the database  
settings your backend uses to connect to the MySQL database is not  
working for MyMote. Usually this is due to the MySQL privileges since  
most MythTV installations do not allow remote connections by default.  
The two things you must do to enable remote access is 1. either remove  
the bind-address line in /etc/mysql/my.cnf or set it to the external  
IP address of your server, and 2. set up the security privileges for  
remote access (http://www.mythtv.org/docs/mythtv-HOWTO-6.html#ss6.2  
under "Modifying access to the MySQL database for multiple systems).  
Then, you have to make sure that your backend settings use the same  
privileges as MyMote can use to access the database remotely. For  
instance, if you have a password for remote access, but none for local  
access, then the backend needs to be using the password. MyMote  
retrieves the username and password that the backend uses to try to  
access the database. To change the database user and password, shut  
down mythbackend, remove ~/.mythtv/mysql.txt for the user mythbackend  
runs as, then run mythtv-setup. It will then ask you for the database  
settings before continuing through the setup screens. Once you've  
connected to the database, you can safely leave mythtv-setup and start  
mythbackend again. You can double check the username and password used  
to connect to your backend at http://<mythbackend address>:6544/Myth/ 
GetConnectionInfo.

2. The issue with the remote not connecting to the frontend sounds  
like MyMote can't resolve your frontend address. Instead of specifying  
hostnames in the MyMote frontend override, have you tried the IP  
address of the frontend? That would at least narrow the issue down to  
name resolution of the frontend by your iPhone or iPod touch.

Lastly, I do troll on the mythtv-users mailing list, but I may not  
always see every MyMote related note. If you want to be sure to reach  
me, CC mymote.support at gmail.com or just post or add a comment to the  
tickets for MyMote.

Thanks,
Chase Douglas
