I doubt that the Dolby SR and CDS theatrical tracks had different sound effects - correct me if I'm wrong, but by 1991, just before the advent of digital 5.1, was there really that much difference between matrixed and discrete mixes other than dynamic range and separation and maybe some extra LFE?

We weren't getting vastly different mixes like in the late 70s, if the silenced gunshots do show up on the theatrical Dolby SR track, they'd have probably have been on the theatrical CDS mix too...right?

Also, you said Rydstrom's near-field remix was done for the SE - wouldn't that mean the pre-2000 theatrical cut releases, or at least the pre-SE ones, weren't remixed for near-field?
