Ok, here is the Verbose output. Audio plays correctly, Video is black (IE, no 
output). Same result without the -nofs display.

Here is (what I think is) the key error message:

Detected video codec: [null] drv:0 prio:0 (NULL codec (no decoding!))

Looking at the FAQ, I'm told to update the codecs.conf file, but that does 
not help.

Here is the console log:

~$ mplayer -nofs -v Video/test.asf
