Going a bit off-topic: Firefox won't play the video. The error console complains about the "Content-Type: video/mp4" header.

I think I found why...
https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats wrote:[10] To avoid patent issues, support for MPEG 4, H.264 and MP3 is not built directly into Firefox. Instead it relies on support from the OS or hardware (the hardware also needs to be able to support the profile used to encode the video, in the case of MP4). Firefox supports these formats on the following platforms: Windows Vista+ since Firefox 22.0, Android since Firefox 20.0, Firefox OS since Firefox 15.0, Linux since Firefox 26.0 (relies on GStreamer codecs) and OS X 10.7 since Firefox 35.0.

So that's why it won't work on XP...

Anyway, if I copy the URL out from the error message then I can play it in VLC player.
(As for why VLC does not have patent issues... see: http://www.videolan.org/legal.html )

I moved posts about MP4 to this new topic from this topic.
