This patch has solved all the MCE remote issues I was having. All the remote functions work now. My "disc menu" button will pop up a menu that allows me to choose between "Top Menu", "Pop-up Menu", "Disc Details", etc. To be honest with you I prefer that behavior instead of having a fixed function to the button such as top menu only or pop-up menu only.
So thank you very much Cyberlink for fixing this issue for me, that I considered to be major.
