I know what I can do, but I would like to see if I can understand what's going on first, before I beat it to death.
I go on line, CNN for example and try to view some of the movie news clips. Sometimes the start out perfectly well, and do not look any different that normal...but then it will switch over to a situation where only certain colours will show, of whole portions that should be a mix of colours are just one colour. It is sort of like looking at a negative or reverse colour arrangement.
I have been following the thread about different file extensions and how they can be tested, but this appears to be a different issue. As I said, it starts out perfectly normal, and then when another vignette starts up it goes completely bonkers...reds are now yellow, blues are black, greens are purple...and so on...
Any ideas as to what's going on?
