After seeing the length of this thread I thought, "oh no, this isn't gonna be easy" but in the end it was a piece of cake to get my Harmony One working with the TiVo box.
The only things I changed from default were:
- Use the big Up/Down buttons as Thumbs Up and Thumbs Down
- Map the Exit button to (return to) TV
- Map bottom-left button to Clear
The one "gotcha" was that I tried to edit the menu buttons from the device and not the activity, but once I remembered that everything was fine.
One issue though: sending a sequence to change channel is extremely slow, much slower that V+ and much slower than just typing in the buttons. I tried setting the delay at 100ms, 0ms, 200ms but this seems to make no difference.
