I have backed it up twice just recently and compared the two. The video does a weird color thing where the colors are almost inverted. the only thing the log says is a av audio sync with some subtitles cause there is none there. but unless there is a menu for more logs thats all i get.

I have successfully backed up all my 4k movies except for the back to the future 4k trilogy. when I back it up every so often in the movie the colors are messed up. I have bought a new copy of them and still got the same issue. Is there anything I can do?

thanks robo
