Meta mail help needed

Hi, I have been recently attempting to configure metamail to
properly launch various windows applications when I receive certain
types of files. An example of this would be my entry to launch the
windows media player when a .wav file is received. Before we go
any further, let me state that I'm using the win95 port of yarn,
and metamail from bellcore.com. I have a 'set
mailcaps=c:\yarn\mailcap' statement in autoexec.bat and have a
mailcat file in my \yarn directory.

Metamail properly recognizes that the file needs to be started with
media player, but for some reason, it does not properly asertain
the correct file name. In stead, it starts media player with a
file such as 'taaa.aaa'. Since this .aaa extension is not
registered to media player, it complains of an invalid file type.
Interestingly enough, if I delete my mailcap entry and attempt to
manually save the file, I get this 'taaa.aaa' as the suggested
"default" file name.

My mailcap file is very simple. The entry in question is:
audio/wav; mplayer %s

In my yarn config file, I have the 'decode-mime=metamail %f' as
suggested. Metamail itself is in my path, so that's not posing a
problem.

Any suggestions would be greatly appreciated. I'm sure that I'm on
the right track, but need help with this last piece.
