I used primarily the 2002 mix because it is lossless. I borrowed sections from the 1997 mix to clean up the edits. I noted some different ADR in the extended cut, so I replaced it back with the original.

I'm aware that not everyone has the capability of playing FLAC 5.1, so I included a lossy DD 5.1 version of the same mix for added compatibility.

I'm only using Adobe Premiere, which does not have native Dolby/DTS output capability. If I could have made clean edits to the Dolby TrueHD track without uncompressing it, I would have. My workaround has been to output each channel as a mono WAV file, and then compile the 5.1 mix in FLAC. At 16bit, I cannot create a 5.1 WAV that's larger than 4GB.

Now that I think about it, I should have included the 1997 mix as a separate track as a courtesy.
