I was wondering if there are 2 ways to encode video on Blu Ray. Sometimes videos are YUV encoded instead of RGB. I wonder if those 2 options are used for BluRay discs as well? If so, can you tell it from some pictogram on the wrapper? Problem is: when I use Mac Blu Ray Player, some movies look excellent, while others have really weird colours. Like NeverTheSameColor analog.... Oversaturated and clipping.
