I've got 2 left, 5 n 6. I've been watching brief clips of each download and I have to say they do look nice. I believe there may have been a bigger source file as the DTS ones use audio from the 2 DVD sets along with the commentaries.
I have NO clue on how to slow them down and replace audio to sync. DoomBot and I have the cinema DTS for Generations through Nemesis but I haven't been able to find Nemesis as of yet.
