Ok I finally understand what it is you are trying to do.
Basically you are showing a way to prevent hotlinking of WMV files and site rippers.
Since there is no javascript or anything like that on your page and your links are not that strange. (href="view.php?file=movies_3/clips/BTG_PBT_Daemon_06_wmv_med.wmv") I would not have a problem with this.
At least not unless someone points something out that I missing. lol
