I found this inside the gatefold of "True Lies" FOXVIDEO 8640-85.

Yep... pretty typical paperwork included in many early AC-3 titles to explain what it is. It's both promotional and a means to educate.

I love stuff like this. Given how common discrete surround sound is today and how groundbreaking it was in the 90s it can almost be seen as a historical document.

Yes, historical indeed.

At that time pretty much every publisher had their own sheet like this. Usually there are graphics. I’d say this one doesn’t do as good of a job of explaining the technology or selling it as others do.

Isn't true lies the first LD release with AC-3RF?
Could be wrong.

Almost, it's Clear and Present Danger (1994) [LV 32463-2WS].
