Symptoms

Movie/cinematics doesn't play at all, but unlike https://github.com/ValveSoftware/Proton/issues/90 it doesn't crash/hangs the game, it just skips the movie and continue as normal

Log:
steam-831560.log

note: unlike https://github.com/ValveSoftware/Proton/issues/90 protontricks 831560 wmp9 quartz devenum doesn't fix the problem

Reproduction

1. Start Warriors Orochi 4
2. press any key -> Gallery -> Movies
3. Try to play any movies and nothing happened, while the movie should play

Start by reviewing steam-831560.log and reproducing the issue through Gallery > Movies in Warriors Orochi 4. Done means the game's movies play instead of being skipped, but the report does not identify a source file or test to update.
