Made a movie from video taken with my sony camera.  When I save it they come up with a file extension of WLMP.  Burned them to a CD to send to my grandkids. Tried to play the CD on my laptop, just to be sure they will play.  No go.  How to I save the movies as mpegs or whatever, so they will play on Windows Media or VLC?     Please and thanks,    John Smyth
