@Billycar11 does it seem plausible that the optics need to be cleaned when it reads all BD and reads older UHD? To be clear it is not a situation where it needs to be re-flashed or updated if that even exists?

There is no error message. The drive just spins and spins and eventually gives up and ejects. Never mounts the disc nor does MakeMKV ever provide an error message.

I tried that. Both discs are brand new. I even returned them both and got new discs. Same thing.

I just tried Avengers: Endgame 4K and it recognized it right away. So just the new ones I'm having an issue with.

Tried that. Still doesn't recognize UHD. Works flawlessly with all BD.

Could it need to updated? or re-flashed?

I know people aren't fans of these LG drives but seems odd that it used to read UHD and works great with BD.

Any reason I suddenly lost the ability to read UHD on a flashed drive? Never had an issue until recently (Oppenheimer & Mission Impossible 7). And I tried multiple discs for each. Won't recognize the disc at all. Just spins and eventually ejects the disc. Drive Information Manufacturer: HL-DT-ST...

It is spinning the disc. Then it makes some weird sounds. Does this for awhile then eventually ejects the disc. I understand a brand new disc can be defective but it is happening with both my new movies Oppenheimer and MI7. Seems unlikely that both new movies are defective. Again, it plays all older...

It's a brand new disc. I just opened it. I tested all my older 4K discs and it reads them. Does the drive have to be updated somehow?

I mean the drive spits the disc out

I have a flashed BD drive WH16NS60 that successfully recognizes and rips other UHD discs but for some reason it won't recognize Oppenheimer or MI:7

Any suggestions?

The tv is a 4K LG. It actually is pretty spot on displaying what the source truly is, 720, 1080, 2160... Why is this movie causing an issue? Never happened before. Really would like it displayed correctly. Without adjusting the tv for 1 movie. Could I compress using something other than H.264?

On my tv it shows as 2160p. Which doesn't make sense. Also, since the black bar around the picture is smaller it appears that the entire frame isn't showing. For example the opening title where it says "The Batman" is stretched and gets cut off a little. Can I alter a setting to keep this ...

The resolution in Plex is saying 720p.

Any way to avoid this from happening? I’ve never had it happen with any other bluray. I use very high settings for limited quality loss

Before compression there is a lot of black around the picture. After compression very little.
