I've got my MX-700 remote programmed with every Tivo code from 1 thru 9. I had to teach the commands to the MX-700 since most remotes only have the basic (0) code in their library. I do a lot of Tivo upgrades and like to temporarily assign codes to the ones I'm working on so they don't interfere with the four Tivos I have active on my system, which is why I programmed all of the codesets in my universal remote.
