Startup Movies not working

I have two startup movies. The first one plays just fine when there is no other video in the array. When I put the second video in, the first one will freeze at the end of it and the game will not launch. Even if I put the same first video twice (to play back to back) it will freeze. Both videos are 1280x720, 24fps, mp4 format, mpeg-4 codec, all the settings that OTHER PEOPLE (not the Epic staff themselves) say to use. The second video I am trying to play contains the UE4 legal information that we are required to display, but at this point I don’t really want to not release my game because the startup movies don’t play correctly (at all really). If there is no UE4 legal information, well, I guess that is their own fault. I can’t believe there is no solid documentation in regards to this.
