OfficeJerk :
Freeware atm. Ive tried out Windows movie maker with no avail.
Free ones to consider:
Lightworks: http

/www.lwks.com/ (there is a free version and the pro version for $60 per year)
Wondershare: http

/www.wondershare.net/ad/video-editor-win/?gclid=C...
ezvid: http

/www.ezvid.com/
I haven't used any of those but since they are free they may be worth a look.
