Yeah, mine's a feckin' coaster as well.
When I loaded it first time, the player (OPPO 4K) just thought about it and then said 'no disc'.
I loaded another blu-ray which I know to be fine and it played fine.
I then reloaded BTLS and it did boot the disc, but was stuck in a one minute clip of Limelight/photo/video montage which recycled endlessly.
What FB page is the thread on and is anyone doing anything about it?
I know someone in the industry who has a bit of leverage with these things, but it's an old title.
Not sure whether that makes any difference. I'll message him.
