Programs transferred easily - Tivo Online - Some programs can not be transferred. I have kept my old Tivo up and running until I watch that the final right protected content. One pass transferred easy - Tivo Online Optimum had to update their host ID to get the cable card to work, some channels were not initially working. When transferring content - Tivo Online, ensure you wait a few seconds on Tivo online before moving pages. This will ensure the transfer makes it way to the the TO Do queue. As long as the items makes to the To Do queue, it will transfer Happy now - 500 GB was not enough space, 2 GB is plenty.
