The LI DVD (1999) of Little Mermaid is 1.66:1 non-anamorphic, unaltered. It's safe in our hands (drf can easily obtain it, and I have a -R).
An OTV is feature enough to make a LD worth buying, if the DVD don't have it.
I've been sourcing my discs at roughly $10 apiece, that's shipping-included, from "Laserdiscs by Duff" on evilBay.
