I was lucky enough to have the “Dr Gonzo” version of the OOT on DVD in the early 2000s. I think it was “Dr Gonzo”, or something similar, a couple of years before the substandard GOUT DVDs was released.

And also the unofficial “Look” 1997 Special Edition on DVD, but I think I only watched them once or twice. It wasn’t good, but it was Star Wars on DVD which was a big thing at the time.

Before I got the “Dr Gonzo” version on DVD I think it was recordings of the films being shown on TV on VHS.
