How to Play Video on the Viewport

I’ve been searching a way to get videos to play on the player viewport, but I’m not having much luck. I’m seeing older videos with a Media Player on an image for a widget BP, but I can’t get it to work. I’m not sure if that method is obsolete.

Have you seen these:

Last time I checked, these worked fine.

The first link helped me get a little closer. I have the new material using the media texture. The texture now appears on the image for my widget bp and the video plays. Now I’m running into another issue. The media player seems to not save the video I set and clears itself upon playing the game in the editor.
