Try going to ( http://slimdevices.com/su_faq.html#t...ng-aacwireless ) as it gives info on plug-in to download for .aac files. It converts them to mp3 on the fly so that they may be played by players that cannot recognize .aac files.

Once you get everything configured properly I am sure that you will be pleased. SlimServer is the main reason that I bought the 770 and all the other benefits are just gravy!
