I have followed the directions in the manual to assign my left and right buttons as well as the mute, channel + -, and volume + -, but they will not work on a global basis, they work when I am on the home page and the mute and channel buttons work on the TV screen but thats it. the left and right buttons only work from the home page. I relabeled these on the home page and the new label does not follow to the other screens, i.e. tv, dvd, etc.. anyone have a cure for this or some info I am not getting correct? thanks in advance!
