    Perplexed by video streaming latency

    I am developing a windows client app that accesses a CCTV video stream from a Linux based back end server app called ZoneMinder. I am using a Web browser control in my Windows client. Specifically, I'm calling the following function:
    Code:
        webBrowser1.Navigate(@"http://XXX.XXXXXX:PORT/index.php?action=login&view=postlogin&username=XXXXX&password=XXXXXX&view=watch&mid=7");
    The above function refreshes the image about once every five seconds. But if I use the native web page front end, the image is refreshed about once every second. That is, if I use firefox or IE to access and display the video stream, the refresh rate is one second.

    So, my questions; why is Navigate so sloooooow? And how can I reduce the time between image refreshes?

    Net version is 4.030319 RtmRel.
