Windows movie maker. You might already have it on your machine if your on win XP or better. Free and easy to use. Bout as easy as a word doc, drag n drop, copy/cut paste. Cake. If you can use Sonar, you can use WMM.
Back n the day i was able to get it off microsifts website, now i think you can only download it with servicepack 2. Search the net, someone might have exe available for download. But it's easy as crap to pick up.
