Re: How do I rename my Fios Set top boxes? When I click on the box name, there is no edit function.

Never mind, I figured it out. 

This is for the new FIOS TV Multi-Room DVR System.

You have to change the STB name on each individual tv.

Then go to:

Main Menu> Settings> System> Media Client Settings> Media Client Name> Modify Media Client

Maybe this will help someone else and save them time trying to find it.
