For a new TiVo Roamio;
Copy down all the info on the cable card, with the cable card OUT of the TiVo, FiOS cable to a 2 way splitter, one leg out to the TiVo the other to the FiOS STB.
Assuming its a new TiVo go through the guided set up except skip the cable card, after the TiVo is up and running, has updated and done what ever it does then install the cable card, your TiVo will go to an installers menu with info you need to give Verizon.
Call Verizon, they will activate the cable card on their end. IF the cable card had previously been in a different TiVo and had been pair to it follow the same steps above.
I did exactly these steps when my Raomio came last week and both my FiOS 7232-2 and my Roamio Pro work fine, no issues on any channel of either DVR.
