Actually, the Atmos mix is a remix of the 2000 remix, it has all the same shitty new aspects of the remix - BUT the 5.1 AC3 included on the same disc is the original 1978 70mm six-track mix, not the 2000 remix!
yea I was a little suspicious about the Atmos mix being from the 2000 remix, but at least the original 1978 mix is included as well on that disk
