Ive got three disc i am having issues with.

Captain Marvel - an early release

Incredibles 2 - again an early release

Walk Hard - an older release.

anyone have ANY suggestions? i really dont want to turn to downloading for my plex server.

Questions:

"Captain Marvel - an early release" - what problems are reported?
"Incredibles 2 - again an early release" - what problems are reported?
"Walk Hard - an older release." - what problems are reported?

Saying it "doesn't work" does not work, because people are just going to guess. And guesses can be bad.

Knowing what kind of problem(s) you're encountering, and how you've already attempted to fix them, does wonders for letting people know what you're seeing.
