Silver that is an error that was never addressed, along with the OHMSS accidental minor edits found on the SE DVD.
I got the whole set recently in decent condition and found I could play back all the discs, even the ones like TMWTGG that are supposedly pressed wrong in places.
None are rotted, and neither is my THX DVD of TSWLM. Maybe you just got some bad discs, but then again they seemed to have lots of trouble with making these.
I now own the remastered NSNA and Casino Royale LDs and have the remastered LTK MGM disc on the way to marathon just before the holidays. I will post in here with results, but these should play exactly like their 1st DVD iterations.
