I live just outside Boston, have FiOS, and will very likely be getting a Roamio Pro pretty soon. I've been reading CableCARD-related threads here and see that it's important to make sure to get a 514517-017-00 card from FiOS. Is that pretty much all FiOS around here is giving out these days, or should I expect to have to bug the store to grab the right one? Also, any recommendations on which FiOS store(s) to go to? Are some better than others or does it not really matter? Thanks!
