I have a copy of Westworld in 1080p. Not sure where I got it from; it may be the previously mentioned HDTV rip. It’s 13gb with DTS 5.1.
I also have the Beyond Westworld, seemingly the same quality as detailed by SKot.
Finally, my copy of Futureworld is 720p, not sure the source. Would be glad to help preserving these any way I can.
