That's what happens when the tape counter runs off the spool drive.
As the tape runs, the diameter of the spool of tape changes, and
the spool rpms change.  *Real* VCRs, like the Sony SL-2700, run
the tape counter off the signals recorded on the tape.  The tape
counter reads in hours/minutes/seconds, and is *correct*.  I doubt
if any VHS machines do this, since the tape has to come off the
head for fast-wind, and you couldn't pick up the timing signals.

Beta HiFi, the system that works.
