Thanks for the test. Finally I use the <video> tag (html5) in both firefox 10 and IE 9. It works natively in IE with an mp4 file (H264/mp4) and in firefox with an ogg file.
Firefox : <video width="400" height="300" poster="myposter.png" controls> <source src="myfile.ogg" /> </video> IE : <video width="400" height="300" poster="myposter.png" controls> <source src="myfile.mp4" /> </video> So I guess the following should work in both, but you have to have two video files : <video width="400" height="300" poster="myposter.png" controls> <source src="myfile.mp4" /> <source src="myfile.ogg" /> </video> Or, last solution : use the ogg file and install ogg codecs in IE.
