Caught glimses of Roots when shown in 1977 (or '78) when I was 12 and of course it had more impact seeing it on DVD over the last couple of days. I was sent the check discs recently and the DVD is out soon. Not a bad transfer. Some grain and edge enhancement. But for £20, the 9 hours and 40 minutes is somewhat like Schindler's List in that it's very moving, humbling and from an educational point of view a must see of the highest order.
