I said it would do basic functions. But it would be like driving a Model T on an interstate. The Hopper remote has so many more functions than the 6.3. The only reason I still have the old VIP remotes is that the installer didn't want them when I got my Hoppers. The basic layout of the Hopper remote is very similar to the 6.3, just has some added keys to take advantage of the Hopper's capabilities. My technophobe wife had no problem switching from a VIP remote to that of the Hopper.
