Sorry to revive an old thread, but just last month I completed my own upscales of both Ewok films (under the pseudonym “Project Ewok”) and both are available on the SWT forums. I see they’re starting to spread around other sites now as well.
Just out of curiosity, did you use the NTSC discs or the PAL discs as a basis for the upscale? Or did you get some other source?
