[mythtv-users] Disable the 'M' and 'I' menus in some screens.

[Chris Tepe]

I'm trying to make myth more friendly for my kids and I was wondering 
how I can disable the 'M" and 'I' context menus in some screens. 
Particular the mythvideo screen. They are always changing the layout and 
then can't find what they want.  But they need the menu option in watch 
recordings to switch between recording groups. So just removing the key 
from lirc file is not an option.
