I have three TVs with QAM tuners connected directly to Fios (no STB). As of 1/9/12, WCAU NBC10 from Philadelphia disappeared from all three TVs. Actually, the HD feed is still there (after a rescan I found it on my Samsung TV as 63-140), but the "mapping" information telling the TV tuner that it is virtual channel 10.1 seems to be missing (as well as all program info). The same applies to 10.2 (it is there as a clear channel but no map to 10.2). All other local channels and sub channels are reported and mapped correctly, and continue as they have for the past several years. I don't really know if this is Verizon's problem of WCAU's, but OTA channel 10.1 is still correctly mapped from broadcast channel UHF 34 along with program data. Since the mapping is different for Fios, however, I suspect a Verizon issue. Can this be verified and fixed ?
