Hi
There's two things to note in the Blu-ray entry for 'New Fist of Fury' (1976): http://dvdcompare.net/comparisons/film.php?fid=52102
The Universal Pictures set is from Scandinavia and based on a 2K master; the German one is from an upscale (same with 'Shaolin Wooden Men': http://dvdcompare.net/comparisons/film.php?fid=52103).
