I have three vcr/dvd recorder players with a digital tuner.I get all of my local channels,but about two weeks ago I couldn't get one of the local channels.This is not on just one vcr,but all of them.They did change one of their antenna tv stations from channel 33-3 channel 15-1.I asked the station on facebook if that could affect my vcr and they said no.Any help would be Greatly Appreciated.
