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.
