CC or Closed Captioning has nothing to do with the remote - it's the text that is sent along with the tv broadcast and is usually enabled by default when the TV sound is muted or it can be turned on and off through the menu system. It displays the text of what the people are saying.

In my opinion you would be better off with a regular harmony rather than the 1000. I do think you can customize the buttons and commands that appear on the 1000 - you just can't do your own layouts and designs like the Pronto.

With the 1000 you get Harmony smart state that controls your equipment power and input settings automatically. With the Pronto you have to do that yourself and it's not easy to do it right. It also takes a lot more programming to customize the Pronto.

If you want a touch screen remote without having to do all the customization and programming then I guess the 1000 would work for you.
