VideoPlayer in MonoGame eats whole RAM, but in XNA don't. How to fix it?

We did a bunch of work on the MonoGame video support and things are better, but still not perfect.

Might want to experiment using our implementations of Video and VideoPlayer for WMS:

SickheadGames/MonoGame/blob/stable_BtA/MonoGame.Framework/Media/Video.WMS.cs

using System.Diagnostics;
using System.IO;
using System.Runtime.InteropServices;
using Microsoft.Xna.Framework.Graphics;
using SharpDX;
using SharpDX.MediaFoundation;
using System;
using System.Collections.Generic;

namespace Microsoft.Xna.Framework.Media
{
    public sealed partial class Video : IDisposable
    {        
        internal Topology Topology { get; private set; }
        internal VideoSampleGrabber SampleGrabber { get; private set; }

        private readonly List<SharpDX.MediaFoundation.MediaSource> _sources = new List<SharpDX.MediaFoundation.MediaSource>();
        
        private static Video PlatformFromUri(Uri uri)
        {

We still feel there are some possible bugs in there, but we’re using it in a project that plays 1000s of videos a day… so it is fairly solid.
