I'm not a Tivo user, but I have a VERY complex system with TV, DVD, CD (3 types), 2 RDAT's, 2 Cassettes, Turntable, pre/proc, 2 VCR's, etc. Even a patchbay 8^) I can tell you I have everything working about 95% of the way I would like and we are working on that last 5%. I have no doubts that it will do everything I want, and though more buttons might be handy, the lack of them is not an impediment to getting all the functionality desired on the Harmony.

There is no problem emulating everything my original DVD remote did. Perhaps others can comment more on the current state of TIVO.
