(oo)
Two of the major encoding schemes, sine wave encoding and synch inversion,
are not compatible with the synchronization circuitry in a VCR.  The
VCR's servo control, which keeps the heads synchronized with the frames
of the picture, depends on a good, undistorted synch pulse to prevent
rolling and blackouts.  This is what add-on "synch stabilizers" take care
of; they reshape the synch pulse sort of like a Schmitt trigger.
