I am running Red October Advanced. I was getting stuttering with automatic video decoder selection so I I opted to manually set my video decoder choice to LAV CUVID. LAV CUVID resolved my playback problem but now when I hit stop either in full screen exclusive mode, or in Theater View it will give the MC is not responding message. If I don't hit stop and instead use exit and exit out to Standard view I can close the Standard Window and MC 17 will shut down okay. If instead I push the stop button on the remote to stop playback in the mini window in the lower left corner of Standard View it will do the hang/crash.
