Hello!
It’s my first day with MonoGame and I wanted to start with a background video running in my Fullscreen window.
What I did: I followed this Tutorial https://msdn.microsoft.com/en-us/library/dd904199.aspx
But the thing is, that the video is not full-screen with that. Not sure how to do that, so I changed the Draw Function from
protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            if (player.State == MediaState.Playing)
                basicEffect.Texture = player.GetTexture();
            // Draw the quad
            foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes)
            {
                pass.Apply();
                GraphicsDevice.DrawUserIndexedPrimitives
                    <VertexPositionNormalTexture>(
                        PrimitiveType.TriangleList,
                        quad.Vertices, 0, 4,
                        quad.Indexes, 0, 2);
            }
            base.Draw(gameTime);
        }
to
 protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            Rectangle screen = new Rectangle(GraphicsDevice.Viewport.X,
       GraphicsDevice.Viewport.Y,
       GraphicsDevice.Viewport.Width,
       GraphicsDevice.Viewport.Height);
            // If the video is playing, get the current frame
            // as a texture. (Calling GetTexture on a stopped
            // player results in an exception)
            if (player.State == MediaState.Playing)
                basicEffect.Texture = player.GetTexture();
            // Draw the quad
            foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes)
            {
                pass.Apply();
                if (basicEffect.Texture != null)
                {
                    spriteBatch.Begin();
                    spriteBatch.Draw(basicEffect.Texture, screen, Color.White);
                    spriteBatch.End();
                }
            }
            
            base.Draw(gameTime);
        }
So it is fullscreen now, but after ~1 Minute my Disk usage raises to 100% and I can’t use my computer and have to restart. The disk is a Samsung Evo SSD so that shouldn’t be a problem. Not sure how to fix this. I just want a background video
