Sorry should have explained more.

The codes do work, but when you enter a code the MX-650 will add the pages for the device and it will add the buttons. The problem is, you cannot rearrange the order of the buttons and you cannot delete specific buttons. The only thing it allows you to do, is change the text. I thought changing to no text would get rid of the button, but it still keeps its function. So I either had to keep it how it was, a complete mess, or do it all from scratch. No way my wife could use the controller if I kept it how it was.

So entered the device code, that put the basics in, then I deleted all the text on all the buttons and removed all the pages except for the first page. Then I typed in each button in the order I wanted, added the extra pages as needed, and then learned the buttons. Looks neat, all the unused buttons are gone and its very easy for my wife to use.
