So...sorry what is the source of this? A Laserdisc pressed in August of 1993? How do you know when this was mastered?

Also, this looks to me like it is the JSC. I think in one of the other threads on SE changes we discovered that the JSC was actually released in the United States as the 1992 LD, so could that be what this is?

I'm a little hesitatant to believe this is just the DC without DVNR, because the colours and video quality don't match at all. Actually, there's an awful lot of video noise on there that makes it look like its actually quite an older master than 1993 (again--1986?).

Some clarrification about the source and format of this and your info might help.
