Free Studio Manager 
The latest version is 4.x. We tried this software since it release v3.x fand found that it was and excellent freeware. The interface was simple but straightforward. Above all, unlike other software, It really worked stably for all open standard multimedia formats.(Your shouldn't expect it worked with patented compressing codec, right?) When converting video files to "flv" or "swf" file, it also generated a sample html code for simple "copy and paste" operation in creating your own web page like commercial software,  We've just downloaded the newest version and found that all collaborating converters're working fine and stable.

Any video converter freeware
If you want to convert a number of video clips concurrently,  AVC freeware is a better choice. Moreover, you have more freedom in the combination of input and output format in the process of convertion. However, we found that it failed the operation for some input formats even we were sure that there was no patented codec applied to the clip.

Pazera Free MOV to AVI Converter 1.2
A very user friendly free file format converter for quicktime movie file for both private and commercial uses. Batch convertion job is possible and the interface is simple and straight forward except the illustration about the choices of audio and video codec. However, you may find out the appropriate combination of file format(avi or mpeg) and codec by trial and error. Use a short clip, run it  and try to play back the converted file accordingly. If it works well, ignore the technical jargon of codec and just stick to the combination that works.
freeware
K-lite Codec Pack
K-Lite Codec Pack is a collection of codecs and related tools provided by free-codecs.com. Now there are too many codecs (encoding and decoding alogrithm) for making and playing back video clips. Though most of them are conformed to open standard, technical novice is hard to know what codecs and how they should be installed. This web site provide a "seem-to-be" simple solution. However, there is little inoformation about the legal status of the codecs included. Some informations told that a few proprietory codec patent holders claimed that the pack violate the EULA or infringe their copyright. The controversal codecs were thus removed from the software afterwards. Users must judge their legitimacy by your ownselves. Furthermore, some proprietory compression algorithms are obstacles for people to play back video files without the proper software. Don't expect to solve all the problems once and forever. As what the site owner tells, you should be able to play 99% of all the movies that you download from the internet with the K-Lite Codec Pack.
