I found a not so good taping of Raiders off TV From Victoria BC from Archive.org And i also found captures of the trilogy from VHS just not the THX tapes. No Laserdisc preservations.

The Trilogy tapes appear to be from the period when Young Indy was on tv because the advert at the beginning of them is for that series. So they aren’t first issue but they also aren’t the THX tapes.

While i was there i also found a superior recording of Warriors of the Wind, from UK Pal tape source. And the 2001 Japan DVD of Transformers the movie with the Japanese Dub. No subtitles and no English track. I didn’t save the link for Transformers because its the same audio as the laserdisc in mono and lossy and its a rip so even worse quality. Its non restored.
