No audio for aac movies

Can anybody help me please. I have a mac and want to be able to convert my movies in order to hear the sound as well. My wd tv live does not work with aac files. What do I have to do? PLEASE ANYBODY HELP. Thank you.

is your audio going through an amplifier? If it is I would say its your amp that doesn’t support AAC. If this is the case you have to change your audio to stereo on the wdtv settings, this means you won’t get dolby digital though.
