I recall there was a Hitachi-made GE VCR top-loader model early '80s that would blank out all the copyguard and other stuff in the vertical interval, even with E-E signals passed through its Video input, so it would be gone when playing back on one of their TVs with the Vertical Interval Reference "VIR" automatic picture control. Seems the wow and flutter time base errors added to the tape playback caused havoc with the TV's VIR working properly, so they just stripped it from the video through that VCR. The mechanically similar Hitachi branded model did not have that.
