I just upgraded to XP SP2 and installed IE 7 at the same time. Both installations went well but there was a problem with IE7. My home page (Road Runner) contains links to AP Video News and CNN Video News. IE7 will not let me play these videos. It puts out a message that says it blocked access to the site because it is an unknown zone. I disabled Zone Alarm and popup blocker but this did not help so I uninstalled IE7 and reverted back to IE6. The problem now still exists in IE6 which it didn't before the upgrade to IE7. Also the problem does not exist if I use Netscape Navigator. So what did IE 7 screw up and how do I fix it?
