      While playing video files, and setting MediaPlayer-elements property loops: MediaPlayer.Infinite, the application crash/stops after some time due to too many files open.

      Running the application in debug mode shows that the application spawns a new thread everytime the video loops, and roughly at around 1000 threads the application crashes.

      I have attached a small running example with a grid view with 9 video elements that loops. Each video is 1 second, and the problem occurs after running the application for approximately 2-3 minutes on my computer. I have also attached a partial  console output from the application.
