Hey DB, your original w64 file synced perfectly to both of my BD's and you're seeing them in perfect sync as well, so no complaints here. In fact, I made a best of disc with all the commentaries and DJ's audio as well as the best remix and they all synced. In the past with other films, I've certainly noticed as little as 250ms mistakes... I mean when it's off it's off and you notice it. DJ's Criterion track via your upload worked like a charm for me. Many thanks to both of you for helping a brutha out.
