Ok, so I've got an embedded flash video player on a site and I've decided to have the source file be a PHP script which redirects to the actual file so anyone viewing the source of the page would see the movie file as "/blah.php?movie=whatever"

I used the header(Location: path_to_movie) method in the PHP script and it works no problem in FireFox, but it doesn't load in Internet Explorer. If I go to the PHP script manually in the address bar it does redirect and brings up the open/save dialog with the actual movie file yet the flash player doesn't work with it.

any ideas or better method for doing this?
