So the 1993 mix found in DE, Faces, and GOUT would have been the first 5.0 mix released followed in 1997 by the 5.0 Cinema DTS and 5.1 Dolby Digital for the SE.
Are you suggesting that the 1993 mix was constructed with stereo surrounds? Because it certainly wasn’t (and couldn’t have been) presented that way - those releases were matrixed 4.0 PCM all the way.
