How would I do that with mplayer?

  mencoder -novideo -oac copy x.wma -o y.wma
->
  WARNING: OUTPUT FILE FORMAT IS _AVI_. See -of help.
  success: format: 0  data: 0x0 - 0x5445000
  ASF file format detected.
  Video stream is mandatory!

Looks like the output format "wma" is not available and that encoding
doesn't work for only audio files. So this is probably not the way to
do it. In the man page and in the online docu I didn't really find an
appropriate method, so I'm grateful for pointers...

Thx,
Gerald

BTW: I'm using "MPlayer 2:0.99+1.0pre8-0ubuntu8" that comes with Ubuntu
Edgy.
