Why? MP4 is a MUCH better compression algorithm. Any particular reason?

the device I want to put it on won't run mpeg-4

What is the device? Maybe I can help. If it is PC related, install FFDShow codecs: sourceforge.net/projects...

QuickTime should open it on Mac, and VLC should open it on ANY platform: www.videolan.org/
