I have a VHS of KotJ from around that time but it’s mono.
My other concerns are around the original music - Dead of Knight specifically. Blu-ray releases to date have had silence where the Prince track should be, followed by some rather prominent clapping.
From what I’ve been told, the BluRay now has the music, but it doesn’t match volume 100% with the original - it goes up and down at different points. It also still has the prominent clapping. It is possible that they have recreated this one too (probably by overlaying the Prince track on the “silent” track). My friend is going to listen to it again and closely compare to my restored version so I wouldn’t take this one as 100% confirmed yet.
As I said, I actually applaud Turbine for putting the effort into these bits, but I think they should be be clear that they are recreations as they are not 100% true to the originals.
KotD - you could be right but I think it’s unlikely. NBC had a definite style to their changes - they were more of a promotional nature. I don’t think the different credits would have been created by them (but I’m only speculating of course!)
