I notice from time to time, when watching TV, my DVR's digital clock reverts back to the station number I am watching and will eventually keep switching from the time to the station number. Is this normal with the FIOS DVR? Perhaps it means information is being transmitted from FIOS headquarters to the DVR? I'm guessing. Happens once in a while, not often, but when it does, it is distracting. I'm not referring to the switch from the time to the station number on the DVR clock, which happens on the hour for one minute, which appears to be normal for the FIOS DVR.
