MP3 movie editor?

I have a 25minute movie I shot with my digital camera. I'd like to edit it down so it's small enough to upload onto YouTube and I can share it with friends. Anyone know of how and with what software I can do this??

Free software advice is welcome.

Go to download.com and search for what you need. When you want to download something it will tell you either it's free, free to try, or a trial period. Or go to goo....i mean yahoo.com and search for what you need...
