They do it the same way my Pioneer CT-9R cassette deck does it: They calculate the amount of tape left on the supply reel by the rotation rates of the supply vs. take-up reel. The VCR only gives it to you in :05 minute intervals, but the cassette deck has it down the the second and both are pretty close. You have to tell the unit when you are using T-160 tapes so that it can adjust the calculation, but it needed to know anyway so it could adjust tape tension."Thank you, Uh Clem." Frank Durda IV @
