I have two displays (dvi monitor and hdmi projector) and when I power on projector then displays swap automatically . If I am watching tv or video I always press stop before swapping and it was enough for MC19 to not crash, but MC20 still crash until after swapping I close it and run again. Before crash it displays "no tuners available". I wrote simple autoit script to restart MC20 and added it to Theater View but maybe you would like to fix this.
