Play m4a files on Windows 7

[J. Landman Gay]

Yes, you're right. We're pretty much screwed then. All the universities 
have demanded that QT be removed from all site computers and our app 
depends on .m4a audio. There are too many audio files to convert to 
another format, and the audio guy refuses to do it anyway due to the 
quality degredation.

We tried installing a codec pack but that didn't work either. We're in 
trouble.
