autoplay and play button do not work for videos

I am trying to play a video (the website supports .webm, .ogv, mp4) but neither autoplay nor the start button seem to work. However, if I slide the control button to the right (+/- 40 sec) the video does play.

I have tried many of the solutions suggested in other threads (deactivating potential conflicting plugins, resetting Firefox, etc.) but none of them work.

What am I missing?

Chosen solution

The problem had an easy solution: changing the order of the videos, listing first the .mp4 source and next the .webm source made the videos run on Firefox, Explorer and Chrome.

Does anybody know why?

additional information: IE, Chrome and Safari work without problems - with Safari using Quick-Time. However on my Android phone I have problems as well. There it seems the video is continuously restarting. The website has the following code:

omitting the brackets:

video width="320" height="240" controls loop autoplay

   source src="http://www.website.com/videos/videoX.webmsd.webm" type="video/webm"
  /source
  source src="http://www.website.com/videos/videoX.ipad3.mp4" type="video/mp4"
  /source
  source src="http://www.website.com/videos/videoX.oggtheora.ogv" type="video/ogv"
  /source
 /video"
