Hello,
I am running Internet Explorer 7 on Mindows XP with service pack 3. My problem is displaying videos from links in internet explorer. I keep getting a message " Internet Eplorer cannot display the webpage. I have run the diagnostic and there is nothing wrong with my connection. I have also checked my security settings as well as Norton Internet Security settings. All seem OK. Am I missing something? This can happen when clicking a video link in an email or a link on a webpage. If the video is part of the webpage, all works fine i.e... YouTube etc. Any assistance would be greatly appreciated.

Try some of the info listed here
You receive an error message in Internet Explorer: "Internet Explorer cannot display the webpage" (http://support.microsoft.com/kb/956196)

Thanks for your reply. I have tried most info in this link but, still no video. I can connect to pages with ease, just not any video links. Other links work fine.

What page are you trying to see video on?
