I (heart) Open Source -- Video Encoding Edition

So I have a need to convert some .AVI files I "obtained" into Quicktime .MOV files. I could never find a decent conversion tool until my buddy Ike started Googling and found ffmpegX. Its a GUI wrapper for the ffmpeg, mpeg2enc, mencoder & other UNIX video conversion tools. It is currently just version 0.0.9s, which means its not totally polished yet. For example, the "progress" window has all sorts of resizing issues when multiple commands are added to it. But it is damn fancy.
