I have win. 8.1 and Windows live movie maker version 2011.  Build 15.4.3502.0922

I upload a AVCHD to Movie Maker.  Movie Maker converts it to a .MTS

You can see thumbnails of the project but when you hit the play button, it doesn't show the video.  Windows 7 worked well.  What do I need to do to make it show up ?

Thank you
