So I was able to successfully stream single player campaign and campaign co-op to my computer using the MCC. Not sure how often I’ll be doing this, but I just wanted to try it, and it was just kinda cool to see Halo on my computer 
During co-op is there any way to get the game to put one player on my computer screen and the other on my tv, so that the two players would both be full screen on their separate screens? I’m guessing the answer is no because the stream is simply replicating the single output from my xbox, but I just thought I would ask. If possible it would be an awesome feature to add!
