Those guys were heroes. They saved much of our cultural history. The FBI should've tracked down those heroes and presented them before The President for decoration! But everyone in government has itchy palms for Hollywood's big bucks. Paid-off Congress voted to further alter and extend the "copyright laws" for Hollywood to keep them forever. What is it now ... 1 or 2 lifetimes of the original author? Legal theft! Copyright law was instituted to offer government protection, for a short time, for the author to profit from his work. IN EXCHANGE, the work would thereafter become "public domain" for the spread and use of those works to ... if I may coin a phrase ... "make America great (again)" and be of value to the rest of the world! Instead, we've got a POLICE STATE tracking down heroes for fines and prison. Disgraceful.

But good to have those extra options available. Thanks!
-- But for a few $$, I can tell you where to get some of the real stuff. 
But they must be better. No super8 film-fade (from that famous film company ... doh!) and perfect-read laserdisc electronics that doesn't cost $$$,$$$ !!
