You are trying to playback a movie through a browser which uses DTS/Dolby sound, No browser support playback of DTS/Dolby sound due to licensing issue. So we request you to either download the movie and playback using VLC player which you can download from http://www.videolan.org/vlc/index.html
alternative to stream you must install Astreamweb application.
For instructions on how to install Astreamweb please checkout solution page: http://astreamweb.com
