This program was found on a dead side of the third disc of "The Choirboys" from MCA DiscoVision.
As this was a dead side, the disc containing this program was likely from a rejected yield. Rejected disc halves were repurposed as dead sides for manufacturing single-sided discs, complete with a layer of residue on the dead side's surface which was meant to prevent that side's playback.
However, this residue can be removed by cleaning it off with isopropanol. Of course, this meant that a person who had the ability to play the content contained therein had content one didn't have the legal right to possess, presenting a problem with regard to copyright law.
This practice was abandoned when MCA DiscoVision and IBM partnered up to form DiscoVision Associates in 1979. The dead sides wound up being transparent discs, allowing people to see the glue used to bond the two disc halves together. The glue had a greenish-brownish appearance, which is dubbed "green slime" by DiscoVision collectors and would often be confused for "laser rot" by those unfamiliar with the intricacies of this format.
The LaserDisc containing this program was played on a Pioneer LD-660. Audio is monaural with no CX noise reduction employed. The program did not appear to have any player control, time and frame codes in the vertical blanking and did not seem to have a data dump on the right analog audio track before the start of the program for interactive functions. The lack of disc coding and the data dump may explain why this disc half was rejected.
When played on either a Pioneer LD-660 or a Pioneer/DiscoVision PR-7820, the disc will start at the beginning and end at the physical termination of the track, barring any defects that could cause a malfunction.
This is a 1978 Chevrolet Pro Serv educational filmstrip "Just a Little Misunderstanding" with soundtrack, produced by the Sandy Corporation for the Chevrolet Motor Division of the General Motors Corporation.
