Hey quality,
We have been working hard to improve upon the Media Framework, and we even removed (very recently) the ability to ‘Stream from Memory’ as this was causing issues with packaged projects. The improvement will be implemented in an upcoming future release.
We are sorry to hear you have moved over to Unity, but we do have another Media Framework feature that can be used as an alternative to the one within the engine. It is an open source VLC media plugin that has stronger video compatibility, but is still in development as well. The issue you mentioned with Ghosting could be unrelated to the Media Player, and more associated with how you are setting up your Post Processing and Materials within your scene. Both of these can have an affect on the overall playback of the video within your scene. If you would like you can create a new AnswerHub post with the issue(s) you are experiencing, provide me with the link in your response to this message, and I will be glad to assist in troubleshooting the issues to help improve upon the feature!
Thank you,
