Help with embedded JW-Player/I-Pad videos not working

Here is the code - might be easier that way:

<br/>
<?php
// Configuration.
$s2_jw_config["jwplayer"] = "/jwplayer/"; // Relative URL path to JW Player files directory.
$s2_jw_config["mp4_video_file_name"] = "Beginners Course/Checkpoint 1/Checkpoint1.mp4"; // Name of your MP4 test file.
// Don't edit anything else below unless you know what you're doing.
?>
<div id="jw-container">JW Player® appears here.</div>
<script type="text/javascript" src="<?php echo $s2_jw_config["jwplayer"]; ?>jwplayer.js"></script>
<?php /* A direct URL to the RTMP source; counting the file against the current User in real-time. */
$cfg = array ("file_download" => $s2_jw_config["mp4_video_file_name"], "url_to_storage_source" => true, "count_against_user" => true); ?>
<?php /* API Function `s2member_file_download_url()` returns false if access is denied to the current User. */
if (($mp4 = s2member_file_download_url ($cfg, "get-streamer-array"))) { ?>
<script type="text/javascript">
jwplayer("jw-container").setup({modes: /* JW Player®. */
[
/* First try real-time streaming with Flash® player. */
{type: "flash", provider: "rtmp", src: "<?php echo $s2_jw_config["jwplayer"]; ?>player.swf",
config: {streamer: "<?php echo $mp4["streamer"]; ?>", file: "<?php echo $mp4["file"]; ?>" } },

/* Else, try an HTML5 video tag. */
{type: "html5", provider: "video",
config: {file: "<?php echo $mp4["url"]; ?>" } },

/* Else, this is a safe fallback. */
{type: "download", /* Download the file. */
config: {file: "<?php echo $mp4["url"]; ?>" } }
],
/* Set video dimensions. */ width: 660, height: 390
});
</script>
<?php } else /* Access is denied to the current User. */ { ?>
Sorry, you do NOT have access to this file.
<?php } ?>

Just had a quick look at the source code on that page, and it appears that you're missing some code there. For example, if you're trying to do the "quick embed" method... then where it says "JW Player appears here", you need to reference the Javascript file AND the video file there (at a minimum). For the regular embed method, it's a lot more code than that.

This page describes both methods in detail...
