Yeah, that was a short scene with Dr. Crusher and Riker talking at a console.
But CBSdigital found the missing film elements after this demo release, inserted it back and in the actual season box and on streaming services the episode is now completely in HD! Same goes for some other scenes that were found AFTER the Bluray boxset releases and those were then also inserted back into the episodes.
For the Blurays it was too late of course, but on streaming those scenes are now HD as well.
Sometimes missing snippets are misplaced into other film cans, where they don't belong. You just have to really search for it. They said in the Bluray bonus material, that they went through hundreds of boxes/tins with cut elements and different angle shots and finally found that missing piece.
So Warners should go back and really look for this stuff, it sure is somewhere to be found!
Until very recently it was said, there could never be an HD release of Dallas at all, because ALL original film was destroyed. What a bs that was.
