Are ASF files supported?

[gaghuman]

I've got a foscam ip camera that let's you stream video from a URL: http://camera/videostream.asf?user=USER&pwd=PASSWORD&resolution=64&rate=0
From what I understand, it's an MJPEG stream. I tried to pass the URL on the "Choose a file" dialog to Videostream but it seems like the browser just starts downloading an ASX file.

Is there a way to stream asf files?

Thanks!
