Yea thats the kind of solution I was looking for crashtest just wondered whether it was available to simply put content-type => flash/swf or whether it'd be more complex really...
To reply to the others I can't stop hotlink access because i'm using the same website as they are, the access rules are a bit more complex than just that. And yes its about bandwidth, I don't care if someone steals my rubbishy 3mb music video (its literally the music with a pic of the album cover on it) its the fact everyone is just abusing my bandwidth and using my video on their own profiles and in all likelihood most people won't go to the effort of stealing mine and hosting it themselves.
