You need to change the IP of your backend in the backend setup

http://www.mythtv.org/docs/mythtv-HOWTO-9.html#ss9.1

Specifically the section about "If you will be deploying multiple 
backends, or if your backend is on one system and you're running the 
frontend on another machine then /do not/ use the "127.0.0.1" IP address."
