How to change mp4 to something...
You dont have to convert them to avi or whatever. Just download the latest version of quicktime pro or realone player and you will be able to play them DivX Player works as well! All of the are availabe as freeware!
If you already have Media Player, go to download.com and search for "MPeggable"... it will install an .mp4 plug-in for MPlayer.
