Note that when I re-tested the problem spots on PS5: Did not try the standard blu-rays, just the 4k UHD discs. Have encountered multiple skips on film #1 close together mid-film, and a relatively lesser one mid-film on film #2 so far. I've only very rarely had issues with 2-3x other discs out of a few hundred dvd's, blu-ray's, 4k's. I thought my player was unable to cope with these disc's format in some way, but I guess that's not the case. I even have the exact same player as the original poster: Sony UBPX800M2. Well, I'm glad Im not the only one then it seems (though still pissed). I'm not sure if its against policy but the email is [' cant return it to the store since it shutdown in January from lack of business caused by covid lockdown measures. I emailed an email listed on warner bros site twice since getting the pack in December. I have not tested the standard Blu-ray films.** ** The pack comes with 8, 4k Blu-ray disks and 8, regular Blu-ray discs. I've watched other movies on the player since and no issues. Something about these movies isn't right. My player has never skipped movies other than these. Loaned movies to a friend for testing, skips on his player too. To troubleshoot I have done the following:

Movie 6: Harry Potter and the Half-Blood Prince - 4k Movie 4: Harry Potter and the Goblet of Fire - 4k

Movie 3: Harry Potter and the Prisoner of Azkaban - 4k Movie 2: Harry Potter and the Chamber of Secrets - 4k This occurs in most of the movies, but mostly evidently in the ones listed below. Problem: The movies freeze for 30-60 seconds and then skip to 2-4 minutes later.

Unfortunately my Harry Potter 8-film collection disk are faulty. please let me know if I should post it in another community.
