If videos do not play upon clicking on them, it may be due to you having IE7 for a browser.


In Windows Internet Explorer 7, go to the Tools menu, select Phishing
Filter, and then click Phishing Filter Settings. In the dialog box that
appears, under Phishing Filter, select Disable Phishing Filter.

or

Open IE7 > Tools > Internet Options 
Click on the "Programs" tab 
Click on the "Set Programs" button 
Click the "Set program access and computer defaults" link 
Click the "Custom" option 
Go down to the "Choose a default media player:" option and select "Windows Media Player" 
Click the "Ok" button 
Close "Default Programs" window 
Click the "Ok" button on the "Internet Options" window
Test this and see if it doesn't get it working for you.  Hope so!


After performing these 1 or both of these steps, you should be able to view videos with IE7.
You are basically wanting to associate a .mpg or .mpeg file with the browser to open in your default video player.
