I just got this remote and I can't get my cable box remote button labeled "All On" that turns on my cable box and tv at the same time learned into the R40. What I really would like to do is turn on the tv then have a 1 or 2 second delay before my cable box comes on because I have a HDMI handshake issue between the two. I really would appreciate any help, maybe even a better way to do this? I need it for my other half :)

Thanks
William
