I can’t find this codec anywhere. I use PotPlayer (with translation patch) to play all my movies since it’s the best player ever (seriously, it’s better than VLC). I got some stuff from iTunes and, well, iTunes player sucks eggballs, so I tried to open them in PotPlayer and apparently iTunes movie files use a magic codec called DRMI that none of my usual codec sources (nor the player itself) can locate.
My only worry is that the “DRM” in “DRMI” stands for what I think it does and it secretly means that I’m accidentally asking for advice to do not very legal things. If that’s the case just point it out and we’ll drop the issue.
