I’m fairly certain it is not; left and right sound identical. Original post updated with media info. The aspect ratio is wrong because the picture is somewhat stretched vertically, but I believe that most of the frame is there. Presumably, the stretching was done so that a person could watch it on a 4:3 CRT TV without having to squint as much.
Thanks for your efforts with this.
I was curious about the sound because there was an article about piracy (can’t find the source now) that was published at the time of AOTC’s release and mentioned the role of “inside jobs” and as an example, described a pirated copy of AOTC that contained excellent fully mixed stereo audio, which led Lucasfilm to conclude it had been shot in a movie theatre/cinema by someone with access to a line output.
That means it’s not the Centropy release but I’m intrigued as to which one it was…
