media textures not showing up in render

I have 2 media textures that are playing windows media files and everything works fine in editor, but when I try to write out frames with matinee, those textures are not showing up.
I tried to change the media texture from play from url to play from memory, but then that caused unreal to crash and now I am unable to open my level at all, it now crashes before loading. Anyone have any suggestions? Thanks
