I hate blueray. At least for having physical copies. Too many times I've tried watching something I own only to have it fail due to my player not having current decryption keys. Perhaps it's more of a player issue and less of a disc issue, but it's still a problem with the overall format.
The one time I actually bought a Bluray, I couldn't play it because of fricking Region Coding. Like this is the 2020s and you still have to deal with that BS?!
MakeMKV hasn't failed me yet. As always, only people fully abiding by corporate rules suffer.
