Something to keep an eye on: apparently Disney started putting the new slipcases onto old stock of The Last Jedi UHD discs. This leads to the discs inside not having all of the special features advertised on the slipcase such as the isolated score.
That seems to have worked, I blame the stupid cardboard sleeves in the Saga collection. It makes it hard to remove the discs without touching the other side.
Unfortunately my UHD disc of A New Hope appears to be defective. Starting from where Luke and Ben see the Falcon the picture freezes then steps forwards for a bit then skips slightly later in the movie where it starts all over again. I put in the new standard Blu Ray to finish watching the movie.
