No worries on the anamorphic issue, msycamore. I was hoping the end result would be resizing the LD transfer to 16:9 eventually. I would experiment with recording the 4:3 analog video output of a DVD player, except macrovision would prevent it.
I am just amazed at how leads keep popping up on this.
I'm also intrigued that this Ebay seller mentions the Italian THX poster as being from 1976.
The IMDB has no info on when the movie opened in Italy though.
