Can you recommend a FREE non-linear video editor program for Windows 7?

I am looking for a Win7 program that can import AVI, WMV, MPEG formats at a minimum; dealing with FLV and SWF would be a plus.

The main thing I need is a simple way to splice clips. I don’t need fancy wipes, fades, etcetera; just the ability to set start and end points on clips and copy/paste them.

I do not want trialware that expires, or “crippleware” that I have to pay to unlock certain codecs. I am looking for full-featured and free.
