Hi Stephen

We've checked the MP4 with MediaInfo, it's all good. We are using this as test page:

We experienced intermittent video loading/playback problems like this in the past.

My suggestion is to start with the Firefox Console and see what pops up when you attempt playback. Hopefully the console will be able to give you more specific information than just failure to load/play the content. Either method below works here:
Menu -> Developer -> Web Console
Ctrl + Shift + K

It might be worth also checking further information on the media itself. In particular, you're looking for the Video and Audio codecs. MP4 is the format of the box holding the content, but not the content itself.:
http://mediaarea.net/en/MediaInfo

There are several references to MP4 not being supported on Windows XP. There may be ways to work around this, but some methods, such as codec packs, may be of questionable legality due to licensing restrictions on specific codecs.

Good luck!

Hi!

I'm having a hard time trying to play MP4 videos in HTML5 pages on Windows XP with FF ESR (either 38.8.x or 45.2.x). Is it possible at all? Chrome on XP plays MP4 just fine. The HTML looks like this:

|<video controls> <source src="bunny.mp4" type="video/mp4"/> </video>|
