Well .asf are windows media player types for audio/video (see their website http://www.microsoft.com/windows/win...spec11300e.asp for more info on this file type ) and show up like that on my searches. Do you have windows media player updated to the newest version yet? do you even use it?

.divx file types are rare really. most people have converted them to AVI or MPG or some other format for better use by known video players.
