Help converting mpeg-4 to avi

I am trying to burn a data disc of 13 t.v. episodes so I can watch them on my divx/xvid compatible standalone dvd player. However one of these files is in mpeg-4 format and cannot be read by my player.(The other 12 are avi's.) Can someone please recommend a freeware or open source program that can easily (one click!) convert this file to a format that can be read by my standalone once burned as data?
I have tried WinAVI Video Converter and a host of other evaluation versions with no usable results. Thank you.

 

hi,

you could try dr divx

or another one i use is mediacoder

mediacoder can transcode to divx in an .avi container

both are free

 

I use alltoavi, its open source but its not a one click wonder. I have had files (h264 files) that I had to convert twice, converting the first file it made finally into a normal avi. It has its quirks, it doesn't like long file names or files deep inside a tree (file in a folder in a folder in a folder etc) and you have to make some choices but it will convert almost anything and has a good help system.

 

Here's a couple more:
SUPER (freeware) http://www.majorgeeks.com/Super_d5117.html
QuickMedia Converter (freeware) http://www.cocoonsoftware.com/index.php?option=com_content&task=view&id=13&Itemid=106

 

Thank you everyone for the help. I will give these apps a try.
