I used to create incredible, custom sound beds, sound clips and mash-ups for PP presentations on the older version of Windows Movie Maker. This does not seem to be available on the 'Live' version. I need to be able to do that with this one. Immediately. I need to be able to add a song and cut it, segue it, overlap the sounds, fade them in and fade them out as I could with the older version. How can I do this in this newer 'live' version?
