Does the DVD mono audio goes out of sync after 16mn? I didn't check, since Dark Jedi file is so much better. Like Stendec, I just erased the MGM Lion roars and synced by -9000, it appears to be in sync as Dark Jedi original file was already synced out to the then current Blu-ray.
I will check about the DVD mono audio, but I don't see why it would desync as both the DVD from 2001 and the recent remaster appears to be the full movie without any frame missing.
