Since the powers to be here and other sites, have a care less!!!! Become what is known as the powers of the people, a PIRATE"!!!!!!!!!!!!!!!! Find any and all sources 16mm, 35mm, VHS, Beta, VCD, DVD, Blu-Ray, Streaming and what ever else is out there. Then, find what the "SUITS" want banned from the internet (programs etc....) that allows capture of the various streams of video and audio and make your own. Yes, for a better phrase I'm a Pirate, and proud of it. In current times it is more difficult than the past.
There is the issue of PAL vs. NTSC, but with experience it can be overcome! Capture, strip and overlay.
The cartoons we seek are out there, not always as good as we collectors like, but with patience you will prevail.
