Some cable TV companies "encode" their signals by reducing the size of
the blanking pulse, which a TV uses for synchronization.  If the VCR's
tuner was more sensitive than the regular TV's tuner, than I suppose it
is possible for the VCR to receive Showtime with the reduced pulses, and
construct a signal the TV can receive when it remodulates the signal onto
channel 3 (or 4).  I have never observed this first hand, however.
