Not sure when this problem occurred since I don't really play WMV files until recently, but I do remember it working correctly before Firefox 4.0. Whenever I load any type of WMV file in Firefox, it doesn't seem to play the files. The "Play" is there, and it seems that the file is completely loaded, but when I press the play button, it says "Connecting", then it doesn't say anything and nothing appears. Before, I would get a message on the bottom telling me the % of the download/stream was buffered, but not anymore. Any idea what the cause of this might be?
