If you want to control any external box using Beo4 then you first need to go the TV's connections menu and see what Set Top Boxes the TV has been 'programmed' to control. Have a look in the 'User' manual at how to 'Register Additional Video Equipment'.  You will have to go through the registration process in order to then see screens like this, showing you what STBs are controllable: Login to view image Or this: Login to view image

Thanks i will check that now ,        

For some reason I thought this function was tucked away in the service menu somewhere. I was pulling my hair out trying to find it as I attempted to get my new-to-me BV7 to play nice with an ATV. I was about to raise hell with my dealer for not actually assigning the inputs/connections/PUCs etc. as I had asked and I thought they fudged it. Turns out they just did the minimum and only updated the PUC library and called it a day. Thanks for posting this, Guy! I'm down to one remote, the greatest remote, my precious Beo4.
