Problem with video on cms

Hello,
I have a problem for a few days, when I integrate a video in the CMS the preview doesn’t shows this video.

If i play the video from my server it work :
http://www.mycd.ma/Dsignage/mycdma/public_ftp/Dsignage_Librairie/Film_Dentiste.mp4
but from the CMS not ???

The older design displays the videos but not the new one ?
iam using chrome

Does it work in the client player?

Layout Preview uses the browsers built in video playback support (HTML5 video) and not WMP. The Player uses WMP.

That being said in my local dev 1.8.1 CMS layout preview does show your video correctly.

Hello peter, but why before it work and now not?
And why the videos inserter more than a month ago sound visible on the layout
