At the readspeed did there by chance was "RipGuard" added after the speed? Seval DVDs I possess have the RipGuard protection, this is, unreadable sectors. And some are placed in the first thousand sectors. With my DVDs MakeMKV also got really slow there, because it skips sector after secto...

Could also go into the advanced options and change the selection rule:

You might have to tick "Expert Mode" in the General tab first to see that tab.

Glad to be of help

Besides, the problem with "Update your player" happened to me in the past as well, when trying to open such a ripped BluRay with VLC Player. So it's not just official players showing that problem.

E.g. DVDfab Passkey can also remove those BD+-things:

MakeMKV only removes AACS as much as I know, not BD+

BD-J Menus never worked for me with anything else than Java 8.

Looking some around, I fine sample files from the Kodi Wiki: https://kodi.wiki/view/Samples#4K_(UltraHD)_Formats
Or you download Big Buck Bunny in 4K from https://download.blender.org/demo/movies/BBB/

Is this by chance a Disney DVD?

Any difference, when you select another Opening Mode? See viewtopic.php?f=7&t=28541

Did you add files or append files? Because if you added files, then basically you have one video with multiple "angles". https://i.imgur.com/gJufzdk.png (https://i.imgur.com/gJufzdk.png if the picture isn't shown) Try adding each title with "Append" to the previous one. For that ...

Glad it worked for you

Quick update. Looks like after a long period of time i was able to rip the disk with dvd decrypter by ignoring the errors. how do i get the episode im having trouble with out of the files is has taken off the disk? Depends how you made the backup with DVDDecrypter. Do you have the VIDEO_TS director...

The current version of MakeMKV can create an ISO of a DVD. Does the error happen there as well? Just enter the DVD and click on the Backup icon on MakeMKV. Could also very much be a copy protection libe ARccOS or RipGuard, though MakeMKV usually detects this. But of course there always can be someth...

Is this a 3D movie? Then you can deselect the "3D" part so to speak.

Example:

(https://i.imgur.com/5VQ9yZi.png if the picture doesn't load)

DVDs usually use MPEG2 for the video tracks
BluRays usually use x264 for the video tracks
UHDs usually use x265 for the video tracks

As already said you can rip the movies and transcode them via e.g. Handbrake.

In the keydb file there are lots of entries for UHD movies.

Though even if you have the VUK, you still need to come around the bus encryption.

There are things like FindVUK which (in this case) depend on DVDfab applications and users working with it.

They read the VUK from the disc and then save them onto an online database.
