I have not tried it yet. But I agree with you that they should add it as a category (I was just thinking that yesterday, when I started playing with the change button). Also it would be cool if there was a way to move functions. For instance when I watch TV sometimes) I am watching a tape at the same time (during the adds I watch a taped show). So I added the VCR buttons (play stop, rewind, FF, rec and pause) I added the Rew FF on Vol + and - since the FF and Rew buttons are used for prev. hour and next hour. But if I can put Prev/next hour on the vol buttons then all my VCR commands will use the right buttons.

(I have not asked Tech sup yet, but I saw your post and decided I might as well post here)
