UPDATES:
I put in sync the italian, french and german audio tracks - for the latter, I was not able to find a 5.1 track, does is exist?
Tomorrow I'll finish the spanish track, plus I plan to capture the commentary track from LD BOX (finally!!!) still shrinkwrapped... it will be a gloriuos day!
I still miss the subtitles tracks, though... any help will be more than welcome!
