Hola,
Si lo que deseas es que alguien de fuera vea videos que estan en tu servidor utilizando paginas de php creadas por ti, hay un buen ejemplo sería el siguiente.

Como ves no es mio, está sacado de la web. Para que funcione necesitarias lo siguiente:
<?php
// include shared code
include_once '../lib/VideoPlayer.php';
// Player contructor
$video_player = new VideoPlayer('video 001.mov', '400', '350', 'true');
  if (!$video_player) {
    die ($video_player->getLastError());
  }  
  /*
   * //Use this method if you use the JW flv player javascript source in your server
   * //Download the javascript source in 
http://www.jeroenwijering.com/?item=JW_FLV_Player   * if(!$video_player->setSwfObject('jw_flv_player/swfobject.js')) {
   *   die ($video_player->getLastError());
   * }
   */
  /// Echo the player method for print the player plugin
  if(!$player = $video_player->player()) {
    die ($video_player->getLastError());
  } else {
    echo $player;
  }
?>
Yo lo he probado, pero deberia sermejorarlo. Por ejemplo, si no se puede ver que te lo indique: No tienes el reproductor adecuado, ...
Espero que te sirva
