I have encoded all of the videos using the Miro converter. The videos work in Safari and Internet Explorer fine, but for Firefox I get the error message "The media could not be loaded, either because the server or network failed or because the format is not supported."
All the videos are saved in the same place so it shouldn't be a server or network failure, and when I use the free VideoJS script with the Miro WebM encoding all works fine.

Any ideas?

Resolved, I forgot to add the MIME types to the server.

Yes indeed - the web server should be configured to serve mp4, ogg and webm mime types.

There are some guides for this:

For IIS:

For Apache:

Just make sure you add all 3 mime types:

.mp4 - video/mp4
.ogg - video/ogv
.webm - video/webm
