Soluzione

MP4 type isn't supported on Firefox! It's only supported in Safari 3.0+, Google Chrome 5.0+ and IE 9.0+! For Firefox you'll need .ogg file or .webm video files as sources! Here is an image containing all supported video formats in HTML 5: table displaying video formats supported by various browsers

And for audio support see this pic:

UPDATE:

Firefox now supports MP4 H.264 (AAC or MP3) https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats

Note: MP4s encoded with a high profile will not run on lower end hardware, such as low end Firefox OS phones.

Firefox gives the error because it doesn't support video/mp4, it's nothing to worry about, something else is causing the problem. You could start by removing one of your two preload attributes although I don't think that's the main problem either.

If you load the webm video directly in Firefox it takes about 30 seconds and after it loads up the play point is right at the end of the video. If you load the ogv file directly it appears to play just fine. I would therefore conclude that there's something wrong with the encoding of your webm file, I'd try encoding it again with some different options.

As a side note, if you can't work out what's up with the encoding, there's really nothing in the video that requires it to be a video. It's basically a video of a slideshow, you might be better off implementing it that way, it would certainly reduce the bandwidth required.
