I find the biggest problem with Lemmy and these federated apps is that search engine indexing kinda sucks right now. They get pushed so far down the bottom of the results, you only really see them when you search site:lemmy.ml or whatever.
I believe this was a good decision. Hopefully in the future search engine indexing will improve. Otherwise I can't see Lemmy being as useful as Reddit.
Is it a new release? Sometimes MakeMKV doesn't have the keys updated on the server for super duper new releases.
When that happens I usually have to go to FindVUK here. Then I place the keydb.cfg file in the directory MakeMKV is installed in. It should be smart enough to detect the keys locally if put in the right location and use those. The updated keys allow it to decrypt these newer disks.
Totally agree, it pains me to see communities move to Discord.
