[Plugin: Shadowbox JS] Shadowbox strips strings from Amazon Secure Link when playing video

Using Shadowbox WordPress Plugin and JW Player WordPress plugin.

In Firefox, when using Amazon dynamic secure links, Shadowbox strips strings from the URL when passing it to JW Player. Works fine on all other browsers, including Opera. So far, it only breaks on Firefox.

Original link on the page’s source code:

<a rel="shadowbox;width=352;height=288" href="http://innovationatwork.s3.amazonaws.com/course/start-here/2-innovation-brain/10.m4v?AWSAccessKeyId=AKIAJM72AUAKKHXGY24A&Expires=1300992974&Signature=wjVT%2fga5AfXm0HZwbtXwYCpIbuI%3d"><img src="http://www.audiotech.com/innovation/wp-content/uploads/2011/01/video-thumbnail.png" alt="video thumbnail Innovation and the Brain" width="180" height="133" title="Innovation and the Brain" /></a>

URL passed to JW Player:
http://innovationatwork.s3.amazonaws.com/course/start-here/2-innovation-brain/10.m4v?AWSAccessKeyId=AKIAJM72AUAKKHXGY24A

I know the issue is with shadowbox because when I embed the player (not using shadowbox), the player handles the link correctly and plays fine.

Any help would be appreciated!
