You can use MM2 to create a WMA file (Microsoft's version of an MP3 file),
You can then use Media Player Version 9 at least, to create a normal audio
CD
First in Movie Maker, drag the VIDEO track over the AUDIO track. you should
then just have an audio track with nothing at all in the video track. You
then save to file in the normal way but what you will get is a WMA file
(just audio)
