I'm sorry to continue to stray from the thread topic and I PROMISE I will stop after this but this IS in defence of a Custom Cover that was called out

I noticed that Cerbero's TR47 covers are still somewhat in error. While the covers say Dolby Stereo Surround Sound, in reality the TR47 discs have 2-channel PCM (uncompressed Pulse Code Modulation) audio only.

YES the TR47 set does have a 2-Channel PCM audio track - THIS IS true.

BUT If the PCM audio is a TRUE copy of the Definitive Collection Laserdiscs THEN the audio IS DOLBY STEREO that is encoded with Dolby Surround. (read the back of the either the Definitive, Faces or the Special Widescreen Edition)

'Dolby Stereo is the name given to the four-channel surround sound developed by Dolby Laboratories and introduced into movie theaters in the 70's. It employed a matrix encoding scheme called Dolby Surround which recorded four channels of information on two channels. The two channels are decoded into L, R, Center and Surround upon playback. The center channel is recorded identically on the left and right channels.'*

Information is from this site

SO the covers are correct
