WMV to MPEG/AVI Converter?

Hey guys, I got a video on my computer from my digital video camera, problem is it’s a WMV and I can’t edit it.

So what’s either a program that will take it off my camera as a MPEG/AVI rather than a WMV?

or

What is a program that can convert WMV->MPEG/AVI?

I found a bunch, but they’re all like $30, and to convert one video… it’s not worth that much. I’d prefer something free :wink:
