Not sure if someone mentioned it already but I've had a lot of success with AVS. Though there is a free version available I believe; just not sure if it's exactly what your looking for.
Hi I will suggest avs converter. Btw, for apple user's, i just discovered the fastest way to convert .avi format to .mp4 app named handbreak
Try FormatFactory. It's free and very useful to convert things back and forth including audio and images.
I use it three years ago, but now it is not really free, for it has the pay version, so I just google and find some other professional video converter, finally i find a Higosoft video converter and then convert my video to swf and flv for Web.
AVS video converter. It is one of the most used. Support most of the video formats i.e, WMV (Windows Media Video), AVI, MPEG 1 and 2, MOV (QuickTime), RM (RealMedia), MP4 (iPod and PSP), DVD and more.
