Ok, what I had to do is go to sources.php and have the mp4 files play with the player.swf and not using th Quicktime script. The player.swf bar has the FULLSCREEN button, but mp4 videos using Quicktime do not.
My original question I guess is how to add the FULLSCREEN button/capability to the mp4 and mp4 remote file types? Under source.php or the Quicktime script?
"mp4" => "
<script type=\"text/javascript\">
QT_WriteOBJECT_XHTML('{SITEURL}/{FOLDER}/{SOURCE}.mp4', '{WIDTH}', '{HEIGHT}', '', 'autoplay', '{AUTOPLAY}', 'bgcolor', '{BACKGROUNDQT}', 'scale', 'aspect');
</script>
