CAA: Christian Anime Alliance

Okay, I've finally completed my movie we've been working on. It's not too great, the acting isn't very good and directing isn't exactly magnificant. BUT it's my first movie to direct, and the actors (My brothers) first time acting.
So the future films will be much better, I believe.

Here's my problem, I edited it in Windows Movie Maker and said Make Movie. The problem is, it only saves it in WMV format...
I need to find a video conversion tool so I can post it on YouTube if I want to.
Any ideas?
Thanks!

I've found a free video converter tool called SUPER: http://www.erightsoft.com/SUPER.html

It can convert just about anything to just about anything (ie. it has a huge range of supported formats). The interface isn't excellent though... Just be careful using it if you intend to open the output file in a picky video editor. *glares in the direction of Premiere Elements*

Other than that, it's really good!
