Although the AC3 is stated as being from the 70mm 6-track, I'm wondering if the PCM on this LD could be based on the 35mm Dolby Stereo mix? That would be interesting.

That is possible, I actually don't remember but I believe both are based on the 6-track, will have to ask him.

Keep in mind that the Surround property of an AC3 stream is purely a flag to tell the decoder to switch to Dolby Pro-logic decoding mode. The audio may well contain matrixed surround information but be missing the flag, if you force Pro-logic decoding you should be able to hear if there are rear channels in the mix.

This was exactly what was going on, I was uncertain at first as I thought it sounded like some of the dialogue came out of the rear speakers when it shouldn't, but it seems to be alright. Thanks.
