One actual calibration question: How in the heck does one do some kind of setting for LD without an actual video essentials LD setting disc?

Wrong thread, actual calibration questions would be better posted in the Technical Discussion forum.

But to answer, some laserdiscs have test patterns or SMPTE colour bars on blank, unused sides. Look through your collection.

And lightguns don't work with HD CRTs, although IIRC there was one for the PS that was designed to work with 100Hz TVs.
