Yes, we know. It's you that doesn't understand. You need to use an IR  
Blaster (http://www.irblaster.info) or connect your myth box to your  
set-top box in some other way (Firewire, USB, serial - whatever your  
set-top box offers). You need to output directly from the myth box to  
your TV. You are the only person using myth and experiencing this  
problem (4 second delays on mouse movement, changing menus). It's  
because you have set it up incorrectly.
