Ingame movies (.wmv)'s not found in built version

]LogWmfMedia:Error: Failed to create source object from URL for X:/Unreal Projects/ProjectFOlder/GameName/Unreal Projects/ProjectFolder/GameName/Content/Movies/LoadScreen1.wmvLogModuleManager:Warning: ModuleManager: Module ‘GameplayDebugger’ not found - its StaticallyLinkedModuleInitializers function is null.

This is the log error that seems to pertain to it. Play in editor the movies plays, but after cook and package it is black.

So,

I did two things.

  1. I added the path to the folder with the media players to always cook.

    [/Script/UnrealEd.ProjectPackagingSettings]
    +DirectoriesToAlwaysCook=(Path=“GameName/UMG”)

  2. I needed to set the play rate to 1.0 in the MediaPlayer and make sure it saved. Half the time I open it, it would be back to 0.0. If it was on 0, then in the packaged game it would not play. Setting the rate to 1 in blueprints didn’t seem to fix this.
