.ogg video not playing in firefox

We're just getting started with html5 video, and cannot seem to get .ogg files to play in Firefox, any tips? Here is the source we are using:

<video width="640" height="360" poster="http://video.thewebreel.com/episode_001/episode_001.jpg" controls autoplay autobuffer>
  <source src="http://video.thewebreel.com/episode_001/episode_001.ogg" type="video/ogg" type='video/ogg; codecs="theora, vorbis"'/>
  <source src="http://video.thewebreel.com/episode_001/episode_001.mp4" type="video/mp4" />
</video>

The live example can be seen here:

However we are totally baffled, everything seems exactly right.

Solution

I uploaded your .ogg to my server suspecting it was a server issue and it's working fine on my server

I'm guessing it's because your web server is replying with

Content-type: binary/octet-stream

Try adding the mime types to nginx...

Open up the Nginx mime type configuration file, eg: /etc/nginx/mime.types

Add these lines after the last video mime type

video/ogg                             ogm;
video/ogg                             ogv;
video/ogg                             ogg;
