Which remote are you using OP?
Logitech Harmony 880. I would like to make the menu/guide pop up when I press guide on the remote.
Not sure what you mean exactly by your second question, do you mean is there a way to mute the audio on DD when playing DVD's? Because you can minimize the window but the audio will still play in the background (i believe) and it would interfere with the audio on your DVD. But once again, i don't totally understand the question so i don't want to confuse anyone.
Right... I was wanting to in some way run DD in the background and watch a DVD... is that possible ? Sounds like that it is not... but hey, it never hurts to ask.

Thanks !
