I'd steer clear of WMM, if you can help it. There are better free editors out there. Not saying I'm an advanced editor or anything, I've just had my share of troubles with it, as many others have. It's ...ok I guess, for someone who's not familiar with any kind of editing, or if you want to do something very simple. I'm not saying don't use it, just don't be surprised if you get frustrated over something little. If you'd like a decent video editor I'd suggest CyberLink Power Director, Sony Vegas, or something along those lines. PM me if you need help attaining one of them.
I'd really love some raw video of decent quality to work with though. I need to work on my editing skills some more, I just don't have any material. I don't have the money to get a decent capture card, and the one I have is having issues with my PC.
