DVD Playback Problem (several films)

[too1vei]

The following movies on licensed Blu-ray discs are freezing in some places during playback:
1. Iron Man
2. oblivion
3. Tron: Legacy
4. The Thing
5. Harry Potter: and the Deathly Hallows, Part One.
6. Underworld
The discs were purchased after they became available in stores. After purchase, the discs have been viewed several times with no problems and have been stored in good condition. Now the player is Oppo UPD-203. I checked these movies/discs on the Denon DBT-3313 player, and hang them in the same places.
Other discs I bought even earlier are playing without problems.

Who else is having this problem? What kind of movies/discs?

At what point is MakeMKV involved in this?

Your description sounds like you're playing the disks and they hit "bad spots", such as scratches or fingerprints. That's not a MakeMKV problem.

I was just hoping that one of the users will tell me something. Sorry if such questions are not discussed

As Woodstock suggested, if the discs are dirty or scratched a player might have trouble playing them. Try gently cleaning the disc.
