Ah, it’s probably Plex not supporting the video’s codec. When you use MakeMKV to generate a video file, it’s basically just grabbing the source file directly from the disc / iso. It’s fine in modern players but for maximum compatibility you’ll have to remux it.

EDIT: Forgot DVDs use a different folder structure than BDs so that guide won’t work, you can use this one from thewiki.moe instead (although it’s very technical, and the wiki is moreso focused on anime.) You can maybe try using ffmpeg to convert to an mp4, that might just make it work on Plex.

DVD -> ISO -> MKV should be fine, what happens when you play the iso directly in VLC?

Hi, I actually wrote a guide on how to do this on my blog: https://nullish.cat/blog/disc-rip/ The gist of it is just MakeMKV (and ImgBurn if you like ISOs.)

You might as well be selling drugs… the only somewhat viable way you could do that is locally and offline in a country that just doesn’t care (so russia or NK.)

As for proposing it, get a different idea. Your uni teacher will 100% reject this one.

happy to be here and not have to pull my hair troubleshooting 😊
