I really like Sony Vegas Movie Studio HD...I use it myself for some simple video editing. IMO, it's a good starter program with the 'Show Me How' tutorials and there's lots of documentation. Plus, there are lots of good tutorials on Youtube. I've tried many consumer grade Video Editors, and I liked Vegas Movie Studio the best and found it to be the most stable out of the ones I've used.
The downside is that it's not free...but depending on your budget, it might be in your price range. Have a look at this link:

Hope this helps. :)
