Why does the programs in Windows Live 2011 have less features to them then Windows Essentials 2012? Like for instance, when I opened a movie or video in Movie Maker 2012, I could hear the audio as I edited the video, but when I open a movie or video in Movie 2011, I can't hear the audio at all. And Movie Maker 2012 saved the video in MP4 format, but Movie Maker 2011 only saved the video in WMV format.
