Some links for working with video.
A blog post about Blender (which is free, GPL) to do video editing.
AVLinux, live-CD for video work: http://www.bandshed.net/AVLinux.html
AVLinux includes OpenShot which is a non-linear editor - http://www.openshot.org/ which looks good too.
Kdenlive - I've seen multiple references to this cross platform OSS video editor. AKC used.
