Black video when opening media with multiple players active

I have an use case that involves having 4 or more MediaElement playing video files. Some video files ar MPEG2 and others are H264. While playing video, when changing media file for some MediaElement, the MediaElement goes black and plays nothing. If I change the media file again it starts working again. I couldnt manage to find reproducible steps, it appears to be random.

Is there any recommendation, or better practice, to implement this use case?

Sorry to not be able to share any reproducible code.

I have a similar application. What I have done is to create a component encapsulating a video player class with its own view model. So multiple instances share nothing on an instance level and they act completely independent . Maybe your implementation needs more separation? Difficult to answer.
