mp4 file converter

Hi all, wonder if you might be able to help. I have an mp4 player which requires me to convert all files to .avi with a file size of under 720 x 480. the company ( nhj ltd) supply you with dr divx to do this but the trial for it has expired Is there anything I have on my computor or can I get something to do the job? I only need to convert very occasionally and, being a yorkshireman, hate to spent money for nothing Any help would be appreciated.

So your saying it is an mp4 player that plays .avi files??? Do you want to change .avi to mp4 or the other way around? If you want it in mp4 try "Videora". It converts videos into mp4, 320x240. It was intended for use with the iPod 5G but it will work for other mp4 players too. It is also free to download and has no usage limit. I hope this helps.

thanks h-bomb. As you probably have sussed, I'm not too litterate in this forum What it is, I have an mpm202 personal player from nhj ltd, Tokyo, and it needs a specific format which dr divx could give me. I was wondering if there is anything (free preferably) which will do the same thing.
