XHTML+SMIL in Service Pack 2 for XP

Hi all

On a machine with Service Pack 2 installed, whenever I tried to play an
XHTML+SMIL file in Internet Explorer, a blue warning bar appeared on the
browser asking something like "do you want to play this active content".
This warning seemed completely indifferent to any of the security settings
one can specify in Internet Explorer.

Has this happened to anyone else?  Might there be a way of stopping this?

While in practice the user can choose to play the file and so is not
prohibited from seeing the content, on the other hand, these warnings will
discourage anyone who is just browsing from curiosity from experiencing
XHTML+SMIL content, since there is no specificity whatsoever to the warning.
