Hi,

This is a problem that arises out of a conflict between a new IE7 Security
feature called "Cross Domain Protection" and the "Local Machine Lockdown"
settings on your machine.

There are two ways to get around this problem you are having linking
directly to a .mpeg file on the web and have it open and play in IE7.

1. You can remove the checkmark in the following:
Tools||Internet Options||Advanced||"Allow active content to run in files on
My computer"
Removing that checkmark enables "Local Machine Lockdown" again, and you
should be able to click on the link you supplied to the .mpeg file and have
it open in the Browser in QuickTime.

2. If you don't wish to enable "Local Machine Lockdown" again(or keep
turning it off and on in order to link directly to .mpeg files on the web),
then you will have to tweak the Registry in order to Opt IE7 out of the new
"Cross Domain Protection" feature as described in the following MS Knowledge
Base article:
http://support.microsoft.com/default.aspx/kb/934366

In other words, you can't have it both ways with IE7. Either you enable
Local Machine Lockdown by removing the checkmark next to "Allow active
content to run in files on My Computer", or, you Opt IE7 out of the new
security feature by using the Registry tweak described at the KB article
above.

Once you've performed either step 1. or step 2. above, you should be able to
click on the link you supplied and see the .mpeg file open up in the Browser
in the QuickTime Player:

Good luck,
