Hi Not sure if anyone will be able to help, but here goes. We were watching The Hunger Games: Mockingjay part 2 on blu ray last week on Panasonic ub400. About 20 minutes in, the disc skipped, and moved to a scene about 40 minutes further on in the movie. We returned too the scene we had been watching, but it did the same again. Took the disc out to see if there were any scratches on it, but it appeared to be in decent condition, apart from a fingerprint. Cleaned the disc, jumped to the same scene again, and again it skipped about 40 minutes forward in the movie. We gave up at that point and ordered a brand new copy from Amazon, with the intention of replacing the disc in the box set. The new disc arrived and we started watching again, but when we arrived at the scene it skipped in the old disc, the exact same thing happened! Given that it was a brand new disc, we tried it on PS4 and it played perfectly. We have had no issues playing 4k discs, but my wife has said that it's been skipping on some discs when she has been watching. Has anyone came across anything like this before?
