FIOS TV recently became available in my area. I now have my installation date for next week to make the switch from Comcast to FIOS. Has anyone made this switch before? and if so, what is the process that I should follow? Do I need to re-run guided set-up prior to the tech installing the new cable cards? I am planning on following the Tivo supplied instructions for the cablecard install, as I did for the Comcast visit back in January. Any advice or suggestions that you could offer would be greatly appreciated. Thanks in advance!!!
