My cableco is currently RCN and my TiVoHD is running with a CableCARD (two S-cards, FWIW). Tomorrow I am switching to Verizon FiOS for TV and internet. Should/can I run GuidedSetup to bring in the Verizon lineup even though I won't have the Verizon CableCARD in place? It would be nice to have the lineup all ready so that once the FiOS tech has finished the install and put in the CableCARD I would be good to go, rather than having to spend an hour running Guided Setup before I can record things. But for some reason I'm under the impression you have to have the new card in place to run GS. Maybe because GS shows you channel previews to help you verify you have the right lineup, and obviously it can't do that w/o a CableCARD in place? If it can be done, I assume the procedure it to pop out the cards, then run Guided Setup to bring in the new lineup? And at that point the TiVo would obviously be useless for recording, though I could watch anything already recorded?
