Technical Question - Streaming MP3s From Amazon S3

I've always used the 1 Pixel Out Audio player for my MP3s.

But for some reason, I can never make it work with Amazon S3 storage on non-Wordpress sites. Is there something obvious that I might be overlooking, cos I've tried everything?

Here's some sample code of what I'm trying to use:

<script language="JavaScript" src="http://mysitename.com/audio/audio-player.js"></script>
<object type="application/x-shockwave-flash"

data="http://mysitename/audio/player.swf"id="audioplayer1"

height="24" width="290">
<param name="movie" value="http://mysitename.com/audio/player.swf">
<param name="FlashVars"

value="playerID=audioplayer1&soundFile=http://Amazon_bucketname.s3.amazonaws.com/mp3filename.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>

So the player files are located on my own webspace and the mp3 is located on my Amazon S3 storage. Is there a way to code this so that it all works? At the moment, the player loads, but hitting play just results in it looking for the mp3 file and then closing.

Another problem is, Amazon S3 says "failed" every time I try to upload the javascript player file, which is why those have to be hosted on my own webspace.

A long, rambling question. Sorry. But this is driving me mad!
