... Could [hypothetically] be done with all three movies, as he has remastered the entire originally trilogy...more than once.

Btw, of course you can use them as you wish but I would highly recommand you don't lose your time with my RotJ version... That's not modesty at all: it really has some abusive settings, and has unfortunately relatively huge clippings in the louder passages. I improved it and corrupted it in the same time ! :/ ... Yeah, sorry.

D_J, for what are your answers about my previous questions well, I don't figure out really what tools are used to manage the mixes for the films. I don't even know if upmixing stereo to 5.1 is done automaticly with a software or if you have to do it with your own hands.

All That I know is that, as I said earlier, if I had to make such upmix for myself I would rebuild the channels in order to bring a new relief through EQ's for each pair of tracks, as for the main center one. Anyway, in the end I may be definitely more interested in stereo.

But I think we'll end that here. It's too much a pain for me to share my point in English ! ;)
