I've had this problem for a while and none of the latest versions has fixed it. When I play a Netflix WatchNow movie in Theater View, whenever I stop the movie (stop button on my MCE remote), MC crashes (black screen, "STOP" appears briefly at the bottom of the screen and then nothing happens, I have to kill the program).
This is the end of the log:
