OK, I've tried the suggestions. I've created a web.config file on my godaddy server. I've added the file type to both the .config and the HTML doc. The strangest thing is that, if I load from Filezila by itself the video will run in Firefox, but if I try to run it through my website on Godaddy it won't work. Did I mention the problem I'm having is with Firefox?
Here's my code;
<aside id="currentMedia">
<video width="420" height="280" controls>
<source src= "video/014_0831m_101.mp4" type="video/mp4" poster="images/Seq014_0831m_Precious.bmp" />
<source src= "video/014_0831m_101.webm" type="video/webm" poster="images/Seq014_0831m_Precious.bmp" />
<source src= "video/014_0831m_101.ogg" type="video/ogv" poster="images/Seq014_0831m_Precious.bmp" />
<p>Your browser doesn't support HTML5.</p>
</video>
</aside>
It's a very simple page. Any suggestion?
