Hi Long Tail Video,
I like your plugin.
I think I find a bug inside JWShortcode.php
We added JW Player or WordPress plugin shortcode with a mp4 video in it, the video plays on Macbooks and PCs, but it shows blank on iPad or iPod or iPhone.
Although HTML5 as default mode, it doesn’t work.
Can you take a look function generate_embed_code($atts) ?
I have modified code for that function so it can plays <video> on iPad or iPod or iPhone
I write the modified code on a blog post, http://pixert.com/blog/mp4-video-cannot-play-on-ipad-ipod-iphone-using-jw-player-shortocode/
I experienced same problem with JW Player for WordPress version 1.5.8
