My video plays OK in every tested browser except IE9 / Windows 7. Please see

The video itself plays in Windows Media Player on a Windows 7 platform.

Can you please help?

Thank you!

We added an .htaccess file in directory that holds the videos.

(It would have been nice if someone from DMX Zone would have resolved this.)

Please read the following:

There are so many pieces to the video puzzle, I hesitate to even bring this up. But it’s important, because a misconfigured web server can lead to endless amounts of frustration as you try to debug why your videos play on your local computer but fail to play when you deploy them to your production site. If you run into this problem, the root cause is probably MIMEtypes.
I mentioned MIME types in the history chapter, but you probably glazed over that and didn’t appreciate the significance. So here it is in all-caps:
What’s the proper MIME type? You’ve already seen it; it’s part of the value of the type attribute on a <source> element. But setting the type attribute in your HTML markup is not sufficient. You also need to ensure that your web server includes the proper MIME type in the Content-Type HTTP header.
If you’re using the Apache web server or some derivative of Apache, you can use an AddType directive in your site-widehttpd.conf or in an .htaccess file in the directory where you store your video files. (If you use some other web server, consult your server’s documentation on how to set the Content-Type HTTP header for specific file types.)
AddType video/ogg .ogv
AddType video/mp4 .mp4
AddType video/webm .webm
The first line is for videos in an Ogg container. The second line is for videos in an MPEG-4 container. The third is for WebM. Set it once and forget it. If you forget to set it, your videos will fail to play in some browsers, even though you included the MIME type in the type attribute in your HTML markup.
For even more gory details about configuring your web server, I direct your attention to this excellent article at the Mozilla Developer Center: Configuring servers for Ogg media. (The advice in that article applies to MP4 and WebM video, too.)

First of all you need to make sure you are using the same software and settings as shown in our users manual.
also please check the htaccess article in our FAQ section:

This is version 1.0.6 and it plays on my development server, even with IE10 (apache) but not on the live site, I tried everything, it plays fine with chrome / firefox but NOT in IE10. I am sure the mime extensions are on the server
