I am trying to deploy my ASP.NET Application which is currently running on Windows Server 2003 32bit and IIS6 to a new Server running Windows Server 2008 R2 and IIS7.My application uses ASP.NET version 4.0 and is working fine on 2003 machine.My problem is:I have deployed the application and it is working fine except that the .flv video is not playing in browserI have added all required mime settings but still no luckwhen i try to run the video i don't get any error just a blank screen showing no video. Same configuration is working on previous machine and the new server is also able to play the video when run from the earlier machine.Please if you have any solution help me out.
