Video Conversion Software

I currently have a few movies that I made on imovie, they are MOV format but I want to convert them to a few different formats like WMV and AVI any suggestions?

I use Squared 5 - MPEG Streamclip video converter for Mac and Windows quite a bit for conversion. I think Handbrake would also do what you want.

Handbrake will, but only older versions, they have ditched AVI all together, Mpeg and MKV only now.
MPEG Streamclip is pretty decent, and, while ugly and a bit dated, FFMPEGX does a good job too.

You'll need the paid version of Flip4Mac for WMVs.

you can probably use something like iSquint or VLC Media Player. Last time I checked, both were free.

Mpeg streamclip is still a great standby, no nonsense converter and should still be free.
